YUKEN S-BSG Low Noise Type Solenoid Controlled Relief Valves S-BSG-03 S-BSG-06 S-BSG-10

The low-noise solenoid controlled relief valve is a combination of a low-noise type pilot operated relief valve and a solenoid operated directional valve. It is used for no-load pump operation by using electric signals or, together with a remote control relief valve, for two or three pressure control of the hydraulic system. 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 5 L/min (1.3 U.S. GPM) and model 10 with 8 L/min (2.1 U.S. GPM). Interchangeability in Installation between Old and New Design. Design 53 valve is one on which DSG-01, design 70 is mounted as a pilot valve. It is interchangeable with old design (design 52) with respect to specifications, exterior shape and mounting dimensions.
