Key Features & Engineering Advantages

• Massive 2000 L/min Flow Capacity: The massive internal galleries are hydro-dynamically optimized to process up to 2000 liters of fluid per minute, ensuring bottleneck-free pressure relief and rapid unloading for massive multi-actuator systems.
• Automated Solenoid Unloading: Equipped with a built-on directional solenoid valve, allowing automated PLC systems to instantly unload the main pump to the tank. This drastically cuts energy consumption, heat generation, and pump wear during idle machine cycles.
• Versatile Main Valve Architecture: Uniquely available in both poppet and spool versions. Engineers can select the poppet version for absolute, zero-leakage sealing, or the spool version for exceptionally smooth, metered pressure transitions without hydraulic shock.
• Dual Precision Adjustment Elements: Choose from two robust adjustment options to set your exact pressure limits across 4 available pressure ratings:
• Adjustable Bolt with Protective Cap: Provides a highly secure, tamper-resistant factory setting.
• Adjustable Handle: Delivers rapid, tactile, on-the-fly tuning in the field.
• Flexible Pilot & Remote Control: Configurable for internal or external pilot oil return, and features an optional remote control port, allowing equipment operators to dynamically adjust system pressure from the cabin or a secondary control panel.
• Heavy-Duty Mounting Options: Available with robust flange connections for secure in-line piping or sub-plate mounting for integration into massive custom manifold blocks.

Ideal Industry Applications:-

The breathtaking 2000 L/min capacity and automated solenoid unloading of the DBW52 Series make it a mandatory primary control component for:
