Product Description

BG BT Hydraulic Pilot Operated Relief Valves

 

Hydraulic Pilot Operated Relief Valves 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.

Remote Control Relief Valves are used for Hydraulic Pressure Control Valve(Relief Valve, Pressure Reducing Valve) by remote control.

Relief Valve is used to protect hydraulic system from excessive pressure and can also beaused to maintain a constant pressure in the hydraulic system.

 

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 diameter 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.

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).

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)
