Product Description
Yuken Type BSG & BST Series Solenoid Controlled Relief Valves
Product Overview: The BSG and BST Series are essential components for achieving pressure safety protection and remote unloading control in industrial hydraulic systems. This series combines a pilot-operated relief valve with a small solenoid directional valve, allowing for automatic system unloading or multi-stage pressure switching via electrical signals. Designed to meet international mounting standards, they are widely used in applications requiring frequent unloading or pressure variations.
This category features a full range of specifications: the subplate-mounted BSG-03 (NG10), BSG-06 (NG25), and BSG-10 (NG32), as well as the threaded-connection models BST-03, BST-06, and BST-10. Renowned for their low noise, high stability, and rapid response, these valves are the premier choice for hydraulic power units (HPUs), machine tools, plastic machinery, and metal processing equipment.
Key Technical Advantages:
Efficient Unloading Function: Combined with solenoid control, it enables low-pressure circulation of the oil circuit without stopping the pump, significantly reducing energy consumption and system heat.
Versatile Mounting Options: The BSG Series offers subplate mounting for easy manifold integration; the BST Series supports threaded connections for convenient standalone circuit installation.
Precision Pressure Control: The pilot-operated structure provides a wide adjustment range with minimal pressure override, ensuring safe system operation at high pressures.
Low Noise Design: Acoustically optimized internal flow paths minimize vibration during switching and relief, improving the overall quality of the working environment.
