We know the consequences of process failure are great, that’s why we have an unwavering commitment to standards and processes that ensure innovative and reliable product designs. Many years from now, as the Fisher™ brand is put onto products, customers will continue to know it stands for integrity.

Type 63EGLP relief valve provides significant overpressure protection for LP-Gas storage tanks. Compared to the Multi-Port Manifold Relief Valves, they have 40% more relief capacity and lower installation and maintenance cost. One relief valve will protect over 3,000 sq. ft of surface area by providing relief capacities exceeding 38,790 SCFM. The unique dual-pilot design allows for the removal of pilot for set point verification and maintenance without having to depressurize tank.

The 289 Series relief valve is a throttling relief valve used downstream of pressure regulators to protect the downstream system from overpressure. A smooth throttling action minimizes pressure surges in the system during emergency operation. These relief valves are available in 1/4, 3/4, 1 or 2 NPT sizes with spring ranges (relief pressure settings) from 5 in. w.c. to 75 psig / 12 mbar to 5.2 bar.

All sizes above 1/4 NPT feature a pitot tube booster for achieving the highest possible relief capacity with a minimum buildup of system pressure. When the valve is opening, high gas velocity through the orifice creates an area of relatively low pressure near the end of the pitot tube. This pitot tube effect forms a partial vacuum above the diaphragm which helps to open the valve.

1805 Series relief valves are designed for use in farm tap applications where a relief valve is needed between the first-stage and second-stage regulators. 1805 Series relief valves are suitable for natural gas, air, propane, or any medium compatible with the internal valve parts. Relief pressures range from 5 to 125 psig / 0,34 to 8,6 bar. Maximum pressure, including buildup, is 150 psig / 10,3 bar.

Fisher 289 Series Relief Valve or Backpressure Regulator are spring-loaded throttling relief valve used downstream of pressure regulators to protect the downstream system from overpressure. 289 Series Valves are ideal for low-pressure settings due to the increased sensitivity provided by a large diaphragm area. Designed for pressure control; they are not ASME safety relief valves.

The Fisher 1805-15 Series Backpressure Regulator / Relief Valve designed for use where a relief valve is needed between the first-stage and second stage-stage regulators. This series of relief valves are suitable for natural gas, air, propane or any medium compatible with the internal valve parts. Relief pressures range from 5 to 125 psig / 0,34 to 8,6 bar. Maximum pressure, including buildup is 150 psig / 10,3 bar.

Post-guiding provides valve plug stability with less chance of a sticking valve plug due to non-lubricating or sticky process fluids or build-up of entrained solids.

The process fluid flows through the trim, flushing away solid deposits above and below the guide bushing, thus reducing the possibility of a sticking valve plug.

Fisher Types 1808 globe-style and 1808A angle-style pilot-operated backpressure regulators or relief valves are economical, compact devices used in gas or liquid service to maintain pressure on oil and gas separators, and in pressure relief applications in gas distribution systems.

Quiet Operation—The Whisper Trim™ cage option can reduce noise from high-velocity gas by as much as 10 decibels. Whisper Trim equipped regulators are especially engineered for high-pressure applications where sonic gas velocities are often encountered at relief valve outlets.

Stable Startup—The unique hollow valve stem in the pilot provides quick pressure registration on top of the main valve plug preventing main valve unseating during normal system startup.

Compact design allows installation where space is a premium. Screwed valve bodies feature compact face-to-face dimensions while flanged valve bodies conform to ISA-75 standards for maximum versatility.

Hammer nut bonnet/body joint allows repair or maintenance with a minimum of tools, without removing the valve body from the piping system. Seat ring can be removed with a standard socket.

Choices of port diameters up to 31.8 mm (1.25 in), end connections, and trim materials suit these valves to many applications, including sour service.

The Series 500 is a modulating, soft-seated pilot operated valve offering premium tightness with the ability to handle temperatures from -65°F to 515°F (-54°C to 268°C). It is designed to decrease leakage associated with metal-seated safety relief valves under extreme operating temperature conditions.

The Sharktooth Control Valve is the first triple eccentric type control valve exclusively designed for process control and throttling purposes. The patented “Throttling Trim Cartridge” creates a valve that exhibits significant improvements in performance, simplicity, and economy. Sharktooth control valves have excellent throttling characteristics and provide aerodynamic noise attenuation and liquid cavitation reductions. They are suitable for a wide range of services from cryogenic temperatures up to 850F for liquids, gasses, and steam.

The Z-Disc technology, invented by Dr. Hans Baumann P. E., enables a low cost, resilient seated butterfly valve the ability to out-perform more expensive style control valves. The unique, patented, shape of the Z-DISC vane offers a number of distinct advantages to the user typically only found in much more expensive style control valves. The unique design produces an equal percent flow characteristic, which allows for a constant gain response throughout the entire opening angle. This produces a linear inherent flow characteristic of the control loop. It also has low breakaway torque and is unaffected by fluid induced dynamic torque problems. The Z-Disc is an excellent low-cost solution for non-extreme flow control conditions.
