    • Asco solenoid valves
      ASCO offers solenoid valves for virtually any application. Models include general purpose, explosion-proof, intrinsically-safe, combustion, and air-operated. They are available in brass, stainless steel, plastic, and aluminum bodies. Enclosures are available to operate from -40°c to 200°c in normal and hostile or explosive enviroments.

      General purpose valves are available to control air, water, light oil, and gases. Pipe sizes of 2 way solenoid valves are available from 1/8" to 3". Pipe sizes of 3-way solenoid valves range from 1/8" to 1". The pipe size range of 4-way valves is 1/4" to 1".

      Air operated valves are designed with a unique sealing member which isolates the pilot air pressure from the main line. Variations in pilot air pressure do not affect valve operation, constant pilot pressure is not required and standard valves will provide long life while handling dry or lubricated air. Available in 2, 3, or 4 way, with brass or stainless steel body. In pipe sizes from 1/4" to 2" NPT.

      Combustion valves are used for shut off and vent valves, to control the flow of fuel oil and gas in industrial boiler/burner applications. Taps in their aluminum bodies allow for convenient routine testing. Aluminum bodies with pipe sizes from 1/2" to 3".

    • Farris Engineering
      Since the early 1940s, the Farris Engineering unit of Curtiss-Wright Flow Control has designed and produced a wide range of spring-loaded and pilot-operated pressure relief valves. Used as safety devices, they prevent overpressurization of vessels, pipelines, and equipment. Farris is a recognized leader in the hydrocarbon processing, refinery, petrochemical, natural gas production and transmission, pharmaceutical, and general processing industries worldwide. A pioneer in the field, Farris Engineering created many products that remain industry standards. Integrating its core hardware technology with the information age, Farris originated computer software to assist customers in the sizing and selection of valves. A recent reorganization of manufacturing plants and processes maximized production effectiveness to position the business unit at the forefront of the industry, with service and delivery second to none.

All stainless, non-flowing pilot controls minimizes product loss and provides maximum resistance to corrosion. Available in Snap Acting or Modulating designs.

      Standard "O" ring elastomer seat main valve and pilot control minimizes fugitive emissions and allows operation within 95% of set pressure. Materials include Viton®, Buna N, ethylene propylene, silicone and Teflon. Optional materials of construction include complete 316 stainless steel.

      Applications: Air, gas, vapor, and liquid services where maximum seat tightness, operating pressures and precise adjustment are required. Excellent for natural gas pipeline and compressor service.

       Series 3800 Modulating Pilot Valve
      Reduce product loss and fugitive emissions with the PCM non-flowing modulating pilot control from Farris Engineering.

      The PCM Modulating Control offers a variety of features and benefits. It opens in proportion to the overpressure to minimize fugitive emissions and product loss as well as to reduce noise. The PCM also reduces the shock loads to vessels and piping systems due to valve actuation. Its set pressure is not affected by constant or variable backpressure. In addition, the PCM Modulating Control can be directly interchanged with our PCF3 snap acting control in the field for both cost and time savings.

      Modulating Pilot Valves:
      • Sizes 1² x 2² through 8² x 10²
