Farris Engineering 27FA45-T40 Safety Pressure Relief Valve 1.5" x 2"

The Farris Engineering 27FA45-T40 is a high-performance safety pressure relief valve designed for overpressure protection in industrial piping systems, particularly in steam, air, gas, and liquid applications. Manufactured by Teledyne Fluid Systems (now part of Curtiss-Wright), this valve features a full-nozzle design with a 1.5-inch inlet and 2-inch outlet, ensuring reliable pressure relief to prevent equipment failure or explosions. Key benefits include ASME Section VIII certification, adjustable set pressures up to 1500 PSIG, and compatibility with corrosive environments due to its stainless steel construction. It offers superior flow capacity (orifice area of 0.503 sq. in.) and quick response times, outperforming similar valves like those from Crosby or Consolidated in terms of maintenance ease and longevity. Drawbacks may include higher initial cost and the need for periodic testing. Ideal for petrochemical, power generation, and pharmaceutical industries, this used unit shows moderate wear but remains functional, with a set pressure of 150 PSIG and cold differential test at 330 PSIG. Advantages over competitors include better back pressure handling and a robust bellows option for variable back pressure scenarios.
