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’s designed to be exchanged with YUKEN S-BSG seriesfor 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.

■ Instructions

●If a remote control relief valve is used in the vent circuit, see page C-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.

●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).
