    General & Chemical Service
  • Pneumatic Control Valve that can be utilized in general service. The body/trim comes in a variety of material selection that includes Ductile Iron ASTM: A395, Carbon Steel (WCB). Model 964 comes in two different seat constructions: metal (Class IV) and a composition seat (Class VI). This model is available in flanged, socket weld, or NPT.
    General Service Linear
  • The Model SCV-30 is a sanitary globe or angle-style control valve for throttling or on/off service. Accessories include pneumatic or electro-pneumatic positioners.
    Low Pressure Sanitary Service
  • The Model SCV-S is a throttling pneumatically actuated control valve designed primarily for clean steam service. It can also be used in liquid and gas applications. With the use of two spring-energized stem seals to prevent leakage into the atmosphere.
    Sanitary Service
  • The Model 3100 end-of-line conservation breather vent is designed for use on atmospheric and low-pressure storage tanks where pressure and vacuum relief are required. Weight-loaded pallets in the vent housing allow the intake of air and the escape of vapors as the tank breathes due to thermal changes and product movement in and out of the tank. The pallets open and close to permit in-breathing and out-breathing necessary to maintain the tank pressure within permissible limits to avoid damage to the tank.
    Pressure/Vacuum Vent
  • The Model 3300 end-of-line conservation breather vent is part of Valve Concepts, Inc. modular vent product line. The Model 3300 can easily be field converted to an end-of-line pressure/vacuum relief vent with the addition of weather hood components or an in-line pressure/vacuum relief with the addition of pipe away body components. 
    Top Mounted Vacuum Relief Vent
  • The Model 6K00 Pressure / Vacuum Vent with Flame Arrestor is designed for use on atmospheric and low-pressure storage tanks where pressure and vacuum relief are required. The model 6K00 is used as an independent safety system to ensure explosion protection. 
    Pressure / Vacuum Vent with Flame Arrestor
  • The Model 3K00 Pressure / Vacuum Vent is designed for use on atmospheric and low-pressure storage tanks where pressure and vacuum relief are required. Weight-loaded pallets in the vent housing allow the intake of air and the escape of vapors as the tank breathes due to thermal changes and product movement in and out of the tank. The pallets open and close to permit in-breathing and out-breathing necessary to maintain the tank pressure within permissible limits to avoid damage to the tank. 
    Pallet assembly Pressure / Vacuum Vent
  • The Model 1049 offers the best pilot-operated vent technology on the market today. The unit allows for bubble-tight seat leakage until the pilot starts to exhaust. At that time, the vent starts to open and is fully open at 10% overpressure. Unlike non-pilot operated units that require substantial overpressure in order to obtain full lift. On Model 1049, the blowdown is limited, and the valve reseats at the set point, where the non-pilot-operated units will go below the set point in order to reseat. 
    Pilot Operated Vent Valve
  • The Pilot Operated Model 5500 conservation pressure vent with pipe-away is intended for use where pressure relief is required and the relieving vapors must be piped away and not emitted into the atmosphere. May also be used for in-line vacuum relief. 
    Pressure Vent w/ Pipe-away Connection
  • The Model 5100 end-of-line conservation breather vent is intended for use on atmospheric and low-pressure storage tanks where pressure and vacuum relief is required. 
    End-Of-Line Relief Vent
  • The Model 5400 is designed for use on atmospheric and low-pressure tanks to reduce environmental emissions and product losses, when operating close to the set point. 
    Pressure Only Relief Vent
  • The Pilot Operated Model 5200 vent provides pressure and vacuum relief in applications that require vapors to be piped away. 
    Pilot Operated Vent with Pipe-Away
  • The Model 4600 spring-loaded vacuum relief vents are intended for use on low-pressure tanks, vapor recovery systems, and process systems where higher vacuum relief is required. 
    Side-Mounted Vacuum Relief Vent
  • The Model 4100 end-of-line spring-loaded conservation vent provides pressure and vacuum relief in applications where higher-pressure settings are required.the model 4100 can easily be field converted to a vacuum-only vent, or a pressure/vacuum vent.
