PVV100 Series

The PVV104 series pressure and vacuum relief vents are used on tank trucks and incorporate roll-over protection.

The PVV104 prevents the build up of pressure and vacuum caused by expansion, contraction and tanker movement.

The PVV104 is designed primarily for thermal relief. The vent incorporates rollover protection by locking shut at any angle greater than 60º from the vertical.

Features & Benefits

Allow excess pressure and vacuum to be equalised through a gauzed flame proof opening.
Aluminium body and Stainless Steel Springs.
All models have roll-over protection ensuring compartment is sealed if tilted more than 60° from vertical.
The PVV range of vents can be mounted inside the tank either on the manhole cover or on a separate flange.
