These Pilot Operated Relief valves are designed to protect the hydraulic system from excessive pressure and can be used to maintain constant pressure in a hydraulic system. Remote control and unloading are permitted by using vent circuits.
a Instructions
a If a remote control relief valve is used in the vent circuit see page 1. 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.
a Pressure is limited by collars fitted. If a working pressure cannot be attained remove some collars. One collar is equivalent to 10 MPa (1450 PSI).
a With a small flow the setting pressure may be unstable. Use models numbered 03 and 06 with a flow rate above 8 L/min (2.1 U.S. GPM) and model 10 with 15 L/min (4.0 U.S. GPM).
a There are two threaded connection pressure ports. They can be connected each other in-line; one as inlet and the other as an outlet or the valve can be used by plugging one of the pressure ports.
