Description

Automatically relieve built up tank pressure with stainless steel vacuum relief valve

Vacuum relief valve stabilizes pressure via preset pounds per square inch (PSI) settings for the the vacuum side and pressure side. When pressure inside tank on vacuum side exceeds 0.15 PSI valve automatically opens for relief, drawing air into the tank. Conversely, when pressure exceeds 15 PSI outside the tank the valve opens and vents air outside. This keeps pressure within tank systems at a desirable level. Use this product in conjunction with sanitary gaskets and single pin heavy duty clamps.

    Are the pressure and vacuum settings adjustable?
  1. Q Are the pressure and vacuum settings adjustable?
    A

    The settings on this pressure relief valve are factory-set and not adjustable.

  2. Can you confirm that the vacuum relief set point is 0.15psi below ambient (0.15psig vacuum)? Is this the initial cracking pressure or the full open pressure? Are there any additional materials that are product contacting besides SS304?

    A

    The vacuum is set to 0.15psi at the manufacturer.  This is cracking pressure to relieve the vacuum and not fully open.  With regards to the material, a gasket would be required to create a leak-proof connection so the material could also come in contact with the gasket as well.  We offer gasket materials of Teflon, Viton, Buna and EPDM.
