PVV200 Series

 

The PVV204 series vents are designed for use on tank trucks which load or discharge with fill caps closed and incorporates roll-over protection.

The PVV204s prevent the build up of pressure and vacuum caused by expansion, contraction and tanker movement.

The PVV204 is designed primarily for thermal relief. The vent incorporates rollover protection by locking shut at any angle greater than 60º from the vertical. 

The vent may also be used on storage and blending tanks. It is important that the pressure/vacuum capability of the tank is known. Different settings may be required.

Features & Benefits
  • Allow excess pressure and vacuum to be equalised through a gauzed flame proof opening.
  • Aluminium body and poppets (S/S also available).
  • All models have roll-over protection ensuring compartment is sealed if tilted more than 60° from vertical.
  • The vent is normally mounted directly to the manhole on the underside of the emergency vent or on a separate weld flange.
  • PVV vents for chemical and stainless steel tanks available.
