Yuken Type BSG Solenoid Relief Valve | BSG-03-2B3B | BSG-06-2B3B-A220 | S-BSG-06 | Low Noise Relief Valve

Yuken Type BSG-03 & BSG-06 Solenoid Controlled Relief Valves

Product Overview: The BSG series is a premium pilot-operated relief valve integrated with a solenoid directional valve, designed specifically for hydraulic pressure control and remote unloading. This series is renowned for its low noise characteristics, high-pressure stability, and long-life switching. By actuating the top solenoid, the system can switch seamlessly between the preset pressure limit and a no-pressure unloading state. Whether utilizing the compact BSG-03 or the high-flow BSG-06, these valves ensure smooth pressure regulation under heavy-duty cycles, making them indispensable for industrial hydraulic power units.

Featured models include: BSG-03-2B3B-A100-60, BSG-06-2B3B-A220-47T, BSG-06-02-D2-30, and the enhanced S-BSG-06-2B3B-D24-N1-L51.

Key Technical Advantages:

• Low Noise Pilot Structure: Optimized damping orifice design significantly reduces fluid noise and mechanical vibration during high-pressure relief.

• High-Response Solenoid Unloading: Equipped with high-performance wet-pin solenoids for rapid electrical response, enabling instant system unloading to protect motors and save energy.

• Wide Range Pressure Adjustment: Smooth knob-style adjustment with secure locking ensures long-term pressure consistency.

• Versatile Electrical Options: Supports A100 (AC 100V), A220 (AC 220V), and D24 (DC 24V) ratings, with various interfaces like standard terminal boxes (N1).
