Farris provides customers with total pressure relief management solutions that support a facilitys entire lifecycle, transforming the way you ensure plant safety.Series 3800 Farris Relief Valves actual orifice areas range from 0.15-109 square inches and can handle pressures from 20-6170 psig and handle -450 F-500 F.
We also offer Farris valve parts, Worcester valve parts, and Worcester positioners. Contact us to find out more about our Farris and Worcester brands. The optional balanced bellows design isolates working parts and top-works from corrosion, and nullifies the effects of back pressure on valve performance. The D to T orifices of the Series 2600 Farris Relief Valves meet API Standard 526 covering orifice areas and center-to-face dimensions. Optional Farris Safety Valves construction materials include 316 stainless steel, Monel, and Hastelloy C. The Farris Safety Valves are available with Farris Valve Parts in compliance with NACE standards. Our dependable and reliable customer service will provide you with the correct Worcester Control Valve for your needs as well as expert advice on Worcester Actuators and Worcester Valve Parts. We offer the same service and expert advice for Sprague Pump Parts, Farris Parts and Flowserve as well as Everlasting Valves, Vogt Valves and Watson McDaniel Valves. The optional manual valve for this purpose mounts directly on the main valve. This pressure acts upon the top of the piston in the dome, holding the piston rmly against the seat on the nozzle in the main valve. The surface area of the piston in the dome of the main valve is greater than the seat area, so the greater the system pressure, the greater the force holding the piston on the main valve seat. Convertible Nozzle: threaded convertible nozzles can be Less Weight, Lower Prole: system pressure provides removed and replaced easily without factory service. They can be installed with common tools while the valve is in line. ![]() Materials certified in compliance with NACE hardness requirements. Teflon for seals required in main valve for temperatures below -20F. Consult the Factory. Teflon used for 0-Fiing Seat Seal (Item 12) for all valves with 900, 1500, and 2500 inlet flanges. ![]() Full 316 Stainless Steel Construction: resists corro sion and extends the life and versatility of the PCF3, HPCF3 Adjustable Blowdown: allows setting blowdown between 3 and 7 of set pressure so that product loss is minimized and fugitive emissions reduced. Viton Seats and Seals: these corrosion-resistant seals and seats enhance valve life. Standard elastomer is Viton which is suitable to a maximum temperature of 450F. For temperatures above 450F, the O-Ring Seals must be specified as Kalrez. The 300 and 600 flanges have identical drilling with flange thickness equal to the 600 class. For liquid service applications, add L to the type number for valves with standard size connections and Y for valves with oversize connections. Example: 38FC10L-120 and 38FC10Y-120. ![]() Standard elastomer is Viton which is suitable to a maximum tempera- ture of 450F. Full port design suitable for use on air, gas, and vapor services only. A 1 X 2 valve is available with an A orifice (0.719 sq. The type number- ing system is ideal as the digits which 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, and spring material, inlet flange class as well as Code liquid design. Farris Relief Valves 3800 Serial Number Must BeParts Replacement Valves: If an exact replacement valve is required, the valve type, size and serial number must be specified to assure proper dimensions and material being supplied. If a specific valve has become obsolete, a recommendation for the current equivalent, Spare Parts: When ordering parts, use part names as listed in the bills of material in this catalog. For Air, Gas Vapor Service: (SCFM) For Vapor or Gas Service: (Lbs.hr.)
