Pilot Operated Relief Valve

1. These valves protect the hydraulic system from excessive pressure, and can be used to maintain constant pressure in a hydraulic system.
2. Remote control and unloading are permitted by vent circuits.
3. Use high venting pressure type to reduce the response time from unload to onload.
4. Sub-plates are available. Specify sub-plate model from the table above. When sub-plates are not used, the mounting surface should have a good machined finish.

Features / specifications

If a remote control relief valve is used in the vent circuit, see page 253 in EIC-C-1001-0. 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 pressure 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 8 L/min. and model 10 with 15 L/min.
