DBW Series Pilot-Operated Solenoid Relief Valves

Product Overview: The DBW series is a high-performance pilot-operated relief valve integrated with a solenoid directional valve. Beyond providing standard pressure limitation and safety protection, it enables remote unloading or multi-stage pressure switching via the top-mounted solenoid. Spanning from Size 10 to Size 30, this series is engineered to handle high-pressure and high-flow conditions with ease. Its modular design makes it a cornerstone for industrial presses, metallurgical machinery, and large-scale Hydraulic Power Units (HPUs).

Featured models include: DBW10B1-52/315-6WE24N9K4 and DBW30-B2-52/315XY 6EG24N9K4.

Key Technical Advantages:

• Solenoid-Controlled Unloading: The integrated directional valve allows for system no-load starting or emergency unloading without altering the primary pressure setting, significantly reducing energy waste.

• High-Pressure Stability: Rated for operating pressures up to 315 bar. The pilot-operated structure ensures smooth pressure regulation and minimal pressure override even at peak flow rates.

• Flexible Pilot Options (X/Y): Supports internal or external pilot supply and drain (X and Y ports), allowing for seamless integration into complex manifold designs.

• Durable EG24 Solenoids: Equipped with 24V DC wet-pin solenoids featuring superior thermal stability and IP65 protection for continuous duty in harsh environments.
