VAV04 Tank Pressure And Vacuum Relief Valve

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