farris safety valve catalog manufacturer

Curtiss-Wright’s selection of Pressure Relief Valves comes from its outstanding product brands Farris, and Target Rock. We endeavour to support the whole life cycle of a facility, and continuously provide custom products and technologies. Boasting a reputation for producing high quality, durable products, our collection of their pressure relief valves are guaranteed to give your equipment and machinery effective relief from pressure when needed.

A pressure relief valve, an umbrella term which includes safety valves and expansion relief valves, is designed to do exactly that: relieve pressure on a system. Pressure reducing valves use spring-loaded mechanisms to control and relieve any excess pressure, and prevent any more fluid passing through until normal pressure conditions have been restored. Depending on the model, control can be provided to both dynamic and static flow conditions.

While some basic components and activations in relieving pressure may differ between the specific types of relief valves, each aims to be 100% effective in keeping your equipment running safely. Our current range includes all forms of valve, from flanged to spring loaded, threaded to wireless, pilot operated, and much more.

Using the power of iPRSM technology and our Farris Engineering Services team, correctly design your pressure relief system to respond to every overpressure scenario. Equip your plant with Farris’ full line of spring-loaded and pilot-operated PRV hardware, knowing your plant is protected by 70 years of manufacturing experience.

2600 Series Design Valve Selection This catalog simplifies the sizing and selection of Series 2600 process pressure relief valves. The pressure relief valves are presented here in an easy-to-understand format. Unless otherwise stated, references made to the Code refer specifically to ASME Section VIII, Division 1. Certified Capacity Code Compliance The Series 2600 pressure relief valves have been carefully constructed and tested in accordance with the requirements of the ASME Pressure Vessel Code, Section VIII. Their capacity rating for the applicable fluids is certified by the National...

2600 Series Construction Resistance to Discharge Piping Strains For most pressure relief valves, and particularly for those from which the discharge must be piped away to a remote location, it is almost impossible to keep piping strains away from the valve. The superior Farris pressure relief valve design incorporates several features which allow this valve to take a maximum amount of piping strain without hampering the functional characteristics of the valve or contributing to serious leakage. 1. The threaded connection between the valve nozzle and the valve inlet flange is located low in...

2600 Series Metallurgy Integral Sleeve Guide The Farris pressure relief valve design incorporates an integral sleeve guide (Fig 5), assuring continual positive alignment after the part has been manufactured, and including the same high corrosion resistant properties in the guide flange that are present in the sleeve portion of the guide. The sleeve guide is extended above the top of the guide flange, minimizing the possibility of corrosive or other foreign particles washing onto the guiding surfaces when the valve is relieving or when it is “breathing” as a result of atmospheric temperature...

2600 Series Operation All Stainless Steel Stem Construction The Farris pressure relief valve design features an all stainless steel stem. This construction cost-effectively eliminates dangerous sticking due to galvanic corrosion at the upper guiding point in the spring adjusting screw. The careful design of this upper bearing also ensures proper alignment and optimum freedom from galling and erratic popping. Positive Connection of Parts The Farris design incorporates a positive connection between the valve stem and the stem retainer as well as between the disc and disc holder (Fig 7). These...

2600 Series Operation Steam Jacketing for Better Heat Transfer In modern process plants, it is necessary to keep some valves and lines warm at all times to avoid solidification of the lading fluid and to guarantee the safety of equipment. Farris offers a steam jacket (Fig 8) to substantially increase the rate of heat transfer into the valve and, at the same time, simplify the problem of removing or dismantling the valve for maintenance. This design offers a separate two-piece jacket that installs on a standard valve body. See details on page 71. Simple, Accurate Adjustments The single Blow...

Definitions Safety Valve – an automatic pressure relieving device actuated by the static pressure upstream of the valve, and characterized by rapid full opening or pop action. Used for steam, gas or vapor service. Relief Valve – an automatic pressure relieving device actuated by the static pressure upstream of the valve, which opens in proportion to the increase in pressure over the opening pressure. Safety Relief Valve – an automatic pressure actuated relieving device suitable for use as either a safety or relief valve, depending on the application. Pressure Relief Valve – a pressure...

Type Numbering System Our type numbering system simplifies the selection and specifying of Farris pressure relief valves because the digits that comprise a specific type number have a distinct significance. The digits describe the basic valve series, orifice, seat and internal construction, inlet temperature range, body, bonnet and spring material, inlet flange class and Code liquid design. H Designates high pressure versions. Used for “Q”, “R”, “T”, & “U” orifices only. Series Number Orifice Areas Orifice Letter E BalanSeal with auxiliary balancing piston F BalanSeal with auxiliary...

Now you can accurately size and select a pressure relief valves for any combination of process applications with SizeMaster™ Mark IV pressure relief valve engineering software. This program for Windows® (all versions) brings unprecedented integration of standard engineering practice to the task of sizing and selecting pressure relief valves.

With SizeMaster Mark IV software, you can define as few as one or as many as 64 different sizing scenarios including blocked flow, fire, thermal and tube rupture, from a scenario matrix grid. Selection of the pressure relief valve is automatically based on the relief area of the worst case scenario. Various Wizards make the most complicated task simple; for instance, the Capacity Wizard allows you to determine accurate vapor generation for vessels of all types.

All sizing equations and selection algorithms are based on ASME Code requirements, API standards and best engineering practice as determined by Farris Engineering. The equations and flow algorithms are internally calculated within an innovative worksheet engine. This worksheet engine also checks parameters and any intermediate calculations against standards’ constraints, letting you know about any non-compliance issues it encounters. All equations, calculations and internal algorithms can be displayed on screen or printed for review.

The engineering worksheet engine also checks your parameters and all intermediate calculations against the standards’ constraints, and it tells you about any non-compliance that it encounters, such as attempting to size a conventional valve when a bellows valve is required.

Once SizeMaster calculates the orifice area required to relieve your process scenarios, SizeMaster guides you through the selection of the appropriate Farris pressure relief valve and its materials and other options.

SizeMaster includes catalogue information for Farris 2600, 2700, 3800, 6400, 6600, 4200, 2800 , and 7200 series pressure relief valves, including their black and white drawings. While you are selecting a Farris type number for a tag, SizeMaster ensures that you don’t pick a valve that is not applicable to your process parameters (such as a liquid-service valve for a vapor scenario), and on-line help is available to assist in the determination of each of the digits of the Farris type number, based on your process scenarios.

From its Quick Size and Capacity Wizards through to its consistently standard Windows user interface, SizeMaster makes the job of sizing and selecting pressure relief valves easy, and its worksheet management and workflow auditing facilities let you ensure that your results are correct.
