Pilot operated relief valves here have been particularly developed as low-noise types. Able to protect pumps and control valves against excessive pressures, they are used to control the pressure in the hydraulic system to a constant level.

三、Instructions
▲Remote control relief valve is used in the vent circuit. In addition, if the internal volume of the vent
line is too large, chattering is likely to occur. Thus, as far as possible reduce the inside Dia. and the length of the pipe.
▲To adjust the pressure, loosen the lock nut and turn the handle slowly clockwise for higher pressures or anti-clockwise for lower pressures. After adjustments, do not forget to tighten the lock nut.
▲Piping of the tank line should not be connected to any tank line of the other valves, but connected directly to the reservoir.
▲With a small flow, the setting pressure may be unstable. Use models numbered 03 and 06 with a flow rate above 5 L/min (1.3 U.S. GPM) and model 10 with 8 L/min (2.1 U.S. GPM).
