Description

Description

When excessive pressure builds within the storage tank the vent’s hinged cover begins to open at the predetermined set pressure, relieving excess pressure.

When the over pressure has dissipated the cover reseats onto the base. The hinge mechanism prevents misalignment and provides an accurate reseat.

When excessive vacuum builds within the storage tank the spring loaded pallet lifts, breaking the seal between the seat and pallet, allowing vapors to pass through the valve orifice relieving the vacuum buildup. The vacuum valve reseals upon relief and remains sealed.
