Applications

  • Designed specifically for use on trailer tanks containing dry bulk products. If a system blockage were to occur, the valves are designed to vent to atmosphere once the valve pressure setting is achieved. The advantage of the adjustable air relief valve is that the factory preset pressure can be tuned by-3/+3 PSI to meet tank/application specific pressure requirements (adjustments should be performed by either the tank builder or tank maintenance facility).

Use

  • Valves have a +1/-0 pressure tolerance (valve opens at set pressure plus 1 PSI) and are adjustable by-3/+3 PSI.
  • Trailer/Tank Mounted

Specifications

  • Relieving capacity: 750 to 1500 SCFM

Features

  • Installed cup seal deters tampering
  • Bayloy body eliminates thread galling
  • The factory preset pressure can be tuned by-3/+3 PSI to meet tank/application specific pressure requirements (adjustments should be performed by either the tank builder or tank maintenance facility).
