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.

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.

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.

UL Listed external relief valves used on ASME containers. The relief valve is held close by the spring force seating the rubber valve disc against the orifice. When the tank pressure exceeds the spring force, the valve disc lifts off the orifice allowing gas to discharge through the valve to the air. When the tank pressure decreases enough, the spring force closes the valve disc back against the orifice stopping further discharge. All working parts of theses valves are outside the container connection so they must be protected against mechanical damage.

Economical: Low initial cost, easy installation, and high capacity per dollar invested reduces total cost of having relief valve capabilities in your system

Durable: Brass body construction and stainless steel spring reduce susceptibility to corrosion damage and the preset, pinned spring retainer prevents relief valve setpoint tampering

AR Valve have formal sales distribution with the Fisher. In addition we work in close co-operation with numerous partnership companies to ensure we are able to offer our customers a complete range of all valve types to meet all applications and service conditions.

Fisher regulators offer pressure and flow control products and solutions in three broad categories - industrial gas and liquids, natural gas and propane gas. Fisher regulators have become the regulator of choice for thousands of installations around the world based on reliability, versatility and rugged construction.

Type 92S control valves and pilot use lapped seating surfaces that have been proven to minimize seat leakage.Types 6492H and 6492L pilots have bellows sealed stems to eliminate stem guide friction. The steel and stainless steel Type 92S control valves are available with a set point range of up to 250 psig / 17,2 bar and a maximum temperature of 650° F / 343° C.

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.
