CONSOLIDATED Maxiflow® high pressure safety valves are premium products that are installed on a majority of power generating stations worldwide to protect boilers from overpressure conditions.

When full lift is attained, (Figure 2), lift stop (M) rests against cover plate (P) to eliminate hunting, adding stability to the valve. When the valve discharges in an open position, steam is bled into chamber (H) through two bleed holes (J) in the roof of the disc holder. Similarly, the spindle overlap collar (K) rises to a fixed position above the floating washer (L). The area between the floating washer and the spindle is thereby increased by the difference in the two diameters on the overlap collar.

Under this condition, steam in chamber (H) enters into chamber (Q) through the secondary area formed by the floating washer (L) and the overlap collar (K) on the spindle, through orifice (N), and escapes to atmosphere through the pipe discharge connection (R). When closing, (Figure 3), the upper adjusting ring (G) initiates the pressure at which the valve will begin to close. The spindle overlap collar (K) is adjusted so that it moves down into the floating washer (L) thereby reducing the escape of steam from chamber (H) effectively. The resulting momentary pressure building up in chamber (H), at a rate controlled by orifice (N), produces a downward thrust in the direction of spring loading. The combined thrust of the pressure and spring loading results in positive and precise closing. Cushioning of the closing is controlled by the lower adjusting ring (O).

OVERLAP COLLAR — controls the pressure at which the valve will reseat. PRESSURE ASSISTED CLOSING — utilizes steam pressure to assist closing the valve and isolates the spring from steam pressure during actuation.

ADJUSTABLE LIFT STOP — matches safety valve capacity to boiler capacity, eliminates overpressure, protects against chatter, reduces reaction forces, assists stack sizing, and protects against over-compression of the spring.

UPPER ADJUSTING RING — for attaining full lift at pop and controlling the pressure at which the valve will begin to close. HIGH CAPACITY DISCHARGE — provides higher rated capacity and increases allowable backpressure to 25 percent of the valve’s set pressure.

THERMODISC — eliminates distortion due to thermal stresses. Temperature differentials quickly equalize and permanent tightness is ensured. LOWER ADJUSTING RING — ensures sharp pop action of the valve on opening and cushions the valve on closing. INLET CONNECTION — welded or flange.

Thermodisc Design The ThermodiscTM seat was designed and developed to address the problem of safety valve leakage. The disc design uses Inconel material and has an improved spindle pocket with concentric loading of the disc. These features, when combined with a low spindle bearing point and a thin flexible seat, provide a superior safety valve that has repeatable seat tightness.

Inconel material provides superior corrosive resistance and strength at high temperatures over a long period of time. The strength of the Inconel material prevents distortion in the spindle/disc contact area during actuation. A more durable disc material helps to maintain the safety valves original set pressure despite numerous actuations and further improves the longevity of the safety valve.

Projected Spring Force Concentric Disc Loading Concentric disc loading equalizes the spring force being transmitted to the valve seating area. The disc remains concentric to the centerline of the valve nozzle and ensures that the valve will reseat in its original seating position. The effective seating area remains constant, producing repeatable valve opening pressures.

Low Spindle Bearing Point A low spindle bearing point locates the point of spring force transmission below the horizontal seat line of the valve, which minimizes the natural tendency for the disc to assume a horizontally tilted position during the opening and closing cycle of the valve. The low spindle bearing point further promotes equalized spring force distribution at the valve seat and contributes to maintaining seat tightness.

Thin Flexible Design The thin seat design compensates for temperature changes by equalizing the temperature in the disc, thereby reducing distortions. Flexibility also allows the system pressure to assist the mechanical loading and produce a line contact at the sealing surface of the seat bushing; the critical seating area remains constant, which ensures consistent repeatable valve opening.

Side Rod Construction The unique side rod construction of these valves insures that spring load in the valve is predictable and does not vary with changes in temperature. The side rods retain spring load and the rods are somewhat removed from the valve body so that the side rod temperatures remain relatively constant. Upon valve actuation, high temperature steam flow through the valve body causes large changes in thermal expansions of materials. The side rods retain their stable temperature and spring load does not change. Body expansion occurs independently of the side rods in an area above the point where the side rods attach to the valve body.

Valve Operation In (Figure 1), the Upper Adjusting Ring (G) is positioned for attaining full lift at pop and for controlling the pressure at which the valve will begin to close. The Lower Adjusting Ring (O) ensures a sharp pop action at the set pressure and cushions the valve on closing.

When full lift is attained, (Figure 2), Lift Stop (M) rests against Yoke (T) to eliminate hunting, adding stability to the valve. When the valve discharges in an open position, steam is bled into Chamber (H) through two Bleed Holes (J) in the roof of the disc holder. The steam escapes to the atmosphere through the Pipe Discharge Connection (R).

ADVANCED YOKE DESIGN — provides spring cooling and ensures stable set pressure. THRUST BEARING — provides accurate and easy adjustment of set pressures when in service, and also provides uniform loading of the valve spring.

VENTED COVERPLATE — allows the valve to go to full lift at 3% overpressure. ADJUSTABLE LIFT STOP — matches safety valve capacity to boiler capacity, eliminates overpressure, protects against chatter, reduces reaction forces, assists stack sizing, and protects against ove-compression of the spring.

GROOVED DISC HOLDER — prevents disc rotation and permits motion with minimum friction. UPPER ADJUSTING RING — for attaining full lift at pop and controlling the pressure at which the valve will begin to close. HIGH CAPACITY DISCHARGE — provides higher rated capacity and increases allowable backpressure to 25% of the valve’s set pressure.

Inconel Disc Material Inconel material provides superior corrosive resistance and strength at high temperatures over a long period of time. The strength of the Inconel material prevents distortion in the spindle/disc contact area during actuation. A more durable disc material helps to maintain the safety valves original set pressure despite numerous actuations and further improves the longevity of the safety valve.

The CONSOLIDATED Series 3500 Electromatic Ball Valve is designed to provide automatic or manual over-pressure protection for steam boiler systems, and can also be used to assist start-up and shut-down venting.

Features & Benefits The CONSOLIDATED Series 3500 Electromatic Ball Valve (EBV) is designed to provide automatic or manual over-pressure protection for steam boiler systems. Set to operate at a lower pressure than the spring-loaded safety valves, the EBV substantially reduces safety valve maintenance and increases boiler efficiency. The EBV should be sized as part of the safety valve boiler package in order to ensure safe performance. This can be accomplished using a Consolidated 3500 EBV because the proper seat bore diameter is selected to match the optimum capacity requirement. Where open/close actuation is acceptable, the EBV can also be used to assist with start-up and shut-down venting.

Ball, Seat, and Seat Loader Assembly The ball, seat, and seat loader is carbide coated which helps to prevent damage caused by abrasives in the steam flow. Also a wiping action occurs as the valve opens and closes which further protects the seats. The ball and seat are made from titanium in order to fight thermal stress cracking, and to improve seat tightness. To further extend the service life of the valve, the ‘seat, ball, and seat loader assembly’ is replaceable in the field.

Seat and Body Joint Seal When it is time to repair the EBV, the ‘seat, ball and seat loader assembly’ can easily be replaced by removing the outlet flange from the valve body. The seat/body joint seal is made of expanded graphite. Expanded graphite provides positive sealing and there is little or no need for lapping surfaces, taking critical measurements and making fine adjustments. This proven method of sealing is also the method with the lowest replacement cost.

LEDEEN® Actuator The LEDEEN actuator is a high quality scotch yoke actuator with several design features not typically found on pneumatic actuators installed in power stations. The rugged frame of the Ledeen actuator is its foundation and is well suited for developing and transferring torque to the valve. Furthermore, the frame is nonpressurized and it is totally weatherproof. This ensures that the rotary seals on the output shaft will not contribute to a pressure leak that would require unexpected maintenance. Inside this frame, every mechanism that slides or rotates during operation has a low friction bushing to efficiently support its movement. In addition, the square slide blocks within the yoke are distinctive and provide a significant stress reduction when transferring the linear input force of the piston into the rotary output of the yoke. In the pneumatic cylinder, a cap seal assembly is utilized on the piston and piston rod. This unique seal design provides a dependable pressure seal specifically designed for dynamic applications that vary widely in operation from low frequency to high frequency. The combination of this seal design with the non-corrosive sealing surface of the cylinder and piston rod ensures extended maintenance free performance. All of the above features on the Ledeen actuator are intended to provide for a long service life.

Control Package Several items have been added to the control package. The positioner monitor is an explosion proof (NEMA 4, 4X, 7, 9 rated) aluminum enclosure and is equipped with two mechanical switches and a high visibility monitor for instant recognition of valve position up to distances of 150 feet. The solenoid valves are mounted directly onto the position monitor housing. This package has the option of adding additional switches should a customer want to send a valve position signal to his DCS or other remote location. Ledeen Actuator

System Components (Figure 1) illustrates the relationship of the various components of the CONSOLIDATED Electromatic Ball Valve System. The Electromatic Ball Valve (EBV) is usually mounted on the superheater outlet header, the controller close to the boiler and the control station on the boiler control panel board. The Electromatic Ball Valve is normally set at a pressure lower than the spring-loaded safety valves where it can substantially reduce safety valve maintenance and improve boiler efficiency.

Electromatic Ball Valve (Type 3500) The CONSOLIDATED 3500 EBV is an automatic, power actuated, pressure relief and venting valve. A double acting air actuator is the standard actuation package. The estimated (open, close) cyclic action is 2 seconds.

Controller (Type 3539) (Figure 2) The standard control package consists of a dual control pressure switch comprised of a bourdon type sensing element that actuates two micro switches and a heavy duty relay switch. When the predetermined set point of the valve is reached, the relay switch closes and transmits electric current to two threeway solenoid valves located on the actuation package. With the solenoid valves energized, the EBV opens. When the pressure decreases below the adjusted closing point of the valve, the relay opens which de-energizes the solenoid valves and causes the EBV to close.

Control Station (Type 2537) (Figure 3) The control station, which includes a switch and two lights, is a small unit that can be mounted on the control panel. The control station is electrically connected to the controller. The control station is a three-position electric switch: off, automatic or manual. With the control station switch in the automatic position, the amber light turns on indicating valve closed and remains on until the valve is opened. When the system pressure reaches the set pressure the valve opens, the amber light turns off, and the red light turns on indicating valve open. When the system pressure decreases to the closing pressure, the valve closes, the red light is turned off and the amber light is turned back on indicating valve closed. When it is desirable to open the valve manually, this can be accomplished by simply pushing the control station switch to the manual position. To close the valve, it is only necessary to push the switch to the off position.

Isolation Valve A special isolation valve is used to isolate the 3500 Electromatic Ball Valve. It must be the correct size and not restrict the capacity of the Electromatic Ball Valve. The valve is used to isolate the EBV in the event of leakage. The isolation valve is normally in the open position during startup.

CONSOLIDATED safety valves are supplied to meet the specific material requirements of our customers. The following special material requirements are available for the safety valves listed. Many boiler manufactures now prefer to match the safety valve inlet neck material to the material being used on the header and nozzle inlet. By matching the materials, welding procedures can be simplified and the overall cost of installation reduced.

Some customers prefer that the valve be supplied with the same material for both the inlet neck and seat bushing. This material combination is often requested when rapid startup is expected on the boiler, as is the case with peaking units. When heat is applied, the expansion rate is constant for both the inlet neck and seat bushing. Both the inlet neck and seat bushing are manufactured from high strength forged material integrally welded to the cast valve body. A Stellite deposit is added to the seating area.

C A U T I O N Steam flow will occur through the coverplate vent when the valve is in the open position. Do not plug. Pipe to safe location. Refer to maintenance manual for instructions.

Hydrostatic Test Plugs For buttweld inlet valves shipped, hydrostatic test plugs are normally installed to increase “set point” approximately 1.5 times the valve set pressure for hydrostatic testing. It is strongly recommended that hydrostatic test plugs be used, in conjunction with proper gag and gagging procedure, during hydrostatic testing to avoid valve component damage. For flanged inlet valves shipped, hydrostatic test plugs are not normally installed. It is suggested that the valve not be installed until after the unit hydrostatic test has been performed utilizing “blind” flanges to blank-off the unit nozzles.

Valves shipped with hydroplug are identified by a Red on White Caution Tag which is attached to the valve by wires extending through the drain hole in the valve body.
