S-BSG Series Low Noise Solenoid Controlled Relief Valves

Product Overview: The S-BSG series is a premium line of pilot-operated relief valves integrated with low-noise technology and solenoid control. By incorporating a specialized silencing structure within the pilot circuit, this series significantly reduces fluid vibration and mechanical noise during high-pressure relief operations. It combines a pilot-operated relief valve with a solenoid directional valve, allowing the system to switch between “pressure regulation” and “no-load unloading” via electrical signals. From the compact S-BSG-03 to the high-flow S-BSG-10, these valves ensure stable pressure management in demanding industrial environments.

Featured models include: S-BSG-10-2B3B-D24-N1-51, S-BSG-03-2B3B-D24-N1-51, and S-BSG-06-2B2B-D24-N1-51.

Key Technical Advantages:

• Superior Noise Reduction: Engineered with “S-type” low-noise pilot heads to suppress cavitation noise under high pressure differentials, improving the operator environment.

• High-Response DC Control: Utilizing D24 (DC 24V) wet-pin solenoids for rapid response, smooth switching, and exceptional electrical durability.

• Versatile Unloading Logic: Available in 2B3B (Normally Regulating/Energized Unloading) and 2B2B (Normally Unloading/Energized Regulating) configurations to suit various system safety requirements.

• Comprehensive Flow Range: Spanning standard interfaces from NG10 to NG32, meeting the flow demands of heavy-duty hydraulic power units.
