APPLICATION

SV-9C series is a pressure adjustable Sanitary Tank Pressure Relief Valve, it is mainly used in pressure vessels or pipe systems. The pressre relief valve has two functions:

● From the Pressure side, when the valve is normally closed and the tank pressure exceeds the rated pressure on the outside of the valve, the valve automatically opens and vents air to atmosphere.

● From the Vacuum side, when the valve is normally closed and there is vacuum in the 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.

HOW TO CALIBRATE

To ajust PRV pressure relief, use a triclamp Tee with gas inlet on one port, pressure gauge and PRV on other 2 port. Wear protect eyeware or face sheild. Set the gas inlet to the desired relief pressure and validated with pressure gauge reading. Adjust with a 3/8″ drive rachet wrench so gas is just leaking out at the desired pressure.

Screw clockwise to increase pressure, anti-clockwise to decrease.
