Weight Loaded.

  • 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 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
  • 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 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
  • 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 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 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 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 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 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.
