  • 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 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 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 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 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 4500 spring-loaded pressure vent with pipe away is intended for use where higher set pressures are 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 with Pipe-Away
  • The Model 4400 spring-loaded pressure relief vents are designed for higher pressure settings and are used in applications for normal or emergency venting pressure relief. The series 4400 vents are pressure-only devices and, as such, do not provide vacuum relief. 
    Spring Loaded Pressure Vent To Atmosphere ( OR) Pressure Relief Vent To Atmosphere
  • The Model 4300 end-of-line spring-loaded vacuum vent is intended for use on storage tanks, vapor recovery systems, and process systems where higher vacuum relief settings are required. 
    End-Of-Line Spring Loaded Vacuum Vent
  • The Model 4200 pipe-away conservation vent is part of the Valve Concepts, Inc. modular vent product line. The Model 4200 can easily be converted to a vacuum-only vent or end-of-line pressure/vacuum vent and can either be direct-acting or pilot-operated. Only Valve Concepts, Inc. offers complete modularity throughout its complete vent product line. 
    Pressure/Vacuum Spring Loaded 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. 
    End-of Line-Pressure/Vacuum Vent
  • 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 3700 manhole and emergency pressure vents provide emergency pressure relief beyond that furnished by the normal pressure vent for atmospheric and low-pressure tanks, as well as providing convenient access for tank cleaning, inspection, and repair. Emergency relief valves provide relief from excessive internal pressure, which an abnormal condition, such as ruptured internal heating coils or an external fire may cause. 
    Manhole and Emergency Pressure Vent
  • The Model 3600 end-of-line conservation breather vent is part of Valve Concepts, Inc. modular vent product line. The Model 3600 can easily be field converted to a pressure-only vent, a pressure/vacuum vent with pipe away, and can either be direct acting or pilot operated. Only Valve Concepts offers complete modularity throughout its complete vent product line. 
    Side-Mounted Vacuum Relief Vent
  • The Model 3500 pressure-only vent with pipe-away is part of the Valve Concepts, Inc. modular vent product line. The Model 3500 is used in the 3200, 4200, and 5200 pressure/vacuum vents with pipe away and the Model 3600 side-mounted vacuum vent. 
    Pressure Relief Vent to Header
  • Model 3400 is lightweight for easy handling, inspection, and maintenance. A coarse mesh screen prevents entry of foreign matter into the seating area. 
    Pressure Vent to Atmosphere
  • 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
  • Cashco’s Model 3200 in-line conservation breather vent is part of the Valve Concepts, Inc. modular vent product line. The Model 3200 can easily be field converted to a vacuum-only vent, a pressure/vacuum vent to the atmosphere, and can either be direct acting or pilot operated. Only Valve Concepts offers complete modularity throughout its complete vent product line. 
    Pressure / Vacuum Vent with Pipe-away
  • The Model 2199 pressure/vacuum relief hatch provides overpressure relief beyond that furnished by the normal pressure vent for atmospheric and low-pressure tanks. The Model 2199 can also be used as a spring-operated conservation vent and tank hatch that provides convenient access for tank cleaning, inspection, and repair.
