Technical Information Fig. 160-2
The Fig. 160-2 range of Relief Valves are of stainless steel construction and suitable for relieving excess pressures of liquids and gases where high discharge rates are not required. The stainless steel construction makes them ideal for use with a wide range of aggressive chemicals and gases.
The valve is supplied with a sealing dome on the adjusting screw to contain any hazardous products
Pressure adjustment is made by unscrewing the sealing dome, slackening the locknut on the adjusting screw, and rotating it clockwise to increase or anti-clockwise to decrease the blow off pressure.
