DA6VP2A-5X/200FSV/60 Rexroth Pressure Cut-off Valve

Product Overview

The DA6VP2, DA6VP1, DA6VP3, DA6VP2A, DA6VP2B and DA6VP2A-5X/200FSV/60 belong to the Bosch Rexroth DA 6 V series of pilot-operated pressure cut-off valves. These valves feature continuously adjustable switching pressure differential (10%–50% of nominal value) and automatically divert pump flow from the actuator circuit to tank when system pressure reaches the set value, providing unloading protection. Fully interchangeable with original Rexroth units, every valve undergoes 100% simulated operating-condition testing for reliable pressure cut-off and energy-saving performance.

Key Technical Advantages

1. Adjustable switching differential: Continuously adjustable from 10% to 50% of nominal value to suit different system requirements.
2. Reliable pilot-operated cut-off: Automatically unloads the pump when set pressure is reached, protecting the system and saving energy.
3. High interchangeability: Identical interfaces and performance to original Rexroth DA 6 V series enable direct drop-in replacement.
4. 100% functional verification under simulated conditions: Every unit is fully tested across pressure switching characteristics before shipment.

Application Areas

• Pressure protection and automatic unloading in hydraulic systems
• Energy-saving circuits on injection molding and die-casting machines
• Machine tools and industrial hydraulic power units
• Actuator circuits requiring pressure cut-off function
• Pump outlet pressure limiting and switching

Expert Maintenance Tips

Ensure the mounting surface is clean and flat; tighten to the specified torque. Maintain fluid cleanliness at ISO 4406 20/18/15. Use correct tools and lock the setting when adjusting pressure. Periodically check set-point and switching action. If switching becomes abnormal, first inspect fluid contamination. For long-term storage keep the valve filled with oil. Always use original-specification seals when servicing.
