PV401 Series

 

Liquip’s PV401 Series of pressure vents are often used on storage tank and limit excess pressure within the tank to 30 kPa max. 

When welded into tank shell, a Ø100mm opening is held closed by a spring within the tank.

When the pressure reaches a pre-determined level (typically 30kPa), a poppet opens and vents the excess pressure to atmosphere. The vent closes and seals at pressures lower than 30 kPa.

PV401 series is available in Aluminium or Stainless Steel cover and Stainless flange. They can be fitted with a choice of Buna nitrile, Viton of Teflon encapsulated O-rings.
