ADJUSTABLE RELIEFS – An adjustable relief valve is standard on all mono-block
directional valves. The standard factory setting is 2, 100PSI @ 8 gpm.
The relief pressure is adjusted by removing Acorn Nut (Parts No.22), and turning the Adjusting
Screw (Part No. 25). Turning the Adjusting Screw clockwise will increase the pressure and counter-
clockwise will decrease the pressure (A pressure gauge must be installed in the inlet line whenever
the relief pressure is adjusted). Adjustable pressure range is 500psi to 3000psi. Do not backout
adjusting screw to the point it falls out.
