Product Description
Rexroth Type DBW20 Series Solenoid Pilot Operated Relief Valves
Product Overview: The DBW20 Series is a high-performance pilot-operated relief valve integrated with a solenoid directional valve, specifically designed for pressure control and safety protection in hydraulic systems. Beyond limiting maximum system pressure, this valve allows for remote unloading via solenoid activation. Fully compliant with ISO 6264 mounting standards, it is an essential component for pressure management in industrial power units.
This category highlights core configurations engineered for diverse electrical requirements: the DBW20B2-5X/315U6EW230N9K4 (Part No. R900942702) for AC systems, and the DBW20B2-5X/315YU6EG48N9K4 featuring DC48V control and external pilot drain (Y option). Utilizing the optimized 5X design sequence, these valves maintain exceptional stability under operating pressures up to 315 Bar.
Key Technical Advantages:
Integrated Dual Functionality: Combines a high-precision pilot relief valve with a solenoid unloading valve into a single unit, simplifying circuit design and minimizing potential leak points.
Flexible Unloading Control: Facilitates rapid switching between the preset pressure and zero pressure (unloading), significantly reducing energy consumption and system heat generation.
Global Voltage Compatibility: Supports multiple power options, including W230 (AC 230V) and G48 (DC 48V), to meet international industrial electrical standards.
Manual Override (N9): Equipped with manual buttons on the solenoid, allowing for manual unloading control during power outages or system commissioning, enhancing serviceability.
