VAV Sanitary Clamp Thread Tank Pressure and Vacuum Relief Valve SS304 Stainless Steel Tank Fitting 1.5"-2.5" or DN20-DN80

Concept

Tank Pressure and Vacuum Relief Valve/Vent is designed to protect stainless tank working in safety. From pressure side, whenthe valve is normally closed and tank pressure exceeds the rated pressure on the outside of valve, the valve automaticallyopens and vents alr to atmosphere. From vacuum side, when the valve is normally closed and there is vacuum in tank, thevacuum piston inside the valve opens automatically and draws air into the tank. in retumn, this keeps the pressure inside andoutside the tank balanced.

Excessive Pressure

Normally closed, but when the tank pressure exceeds the rated pressure.the valve automatically opens to vent air out.

Vacuum

Normally closed,but when there is a vacuum in the tank,the vacuumpiston opens automatically,drawing air into the tank. Thus, keepingpressure balanced inside and outside the tank.
