Regenerative and Hybrid Pilot Operated Directional Control Valve - Series D*1*WR/Z
*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.
Parker's series of regenerative and hybrid pilot operated directional control valves D*1*WR/Z makes energy savings with valve-controlled linear cylinder actuators easier than ever before. The innovative integrated regenerative function in the A-line enables efficient circuits with differential cylinders. The hybrid version allows additionally to switch freely at any time for maximum energy savings without restricting the operating range.
The series of regenerative and hybrid valves is available in four sizes:
• D31NWR size NG10 (hybrid function with adaptor plate)
• D41VWR, D41VWZ size NG16
• D91VWR, D91VWZ size NG25
• D111VWR, D111VWZ size NG32
Markets:
• Industrial
Features/Benefits:
• Proven robust design that represents our long-term experience in hydraulics
• High functional limits – low forces resulting in safe operation also at high flow rates
• Low pressure drop – resulting in low energy losses in operation
• Innovative A-regeneration - provides increased energy efficiency by reducing the oil requirement for partially-loaded differential cylinders
• Switchable hybrid version - can switch between regenerative mode (for high velocity) and standard mode (for high force)
• Short delivery time - no warehousing necessary
Applications:
• Suitable for general hydraulic applications
• General presses
Info regenerative and hybrid function:
In applications with differential cylinders it is common to feed the return flow from the rod side of the cylinder back to the piston side to achieve higher velocity or lower pump flow. Parker differentiates between regeneration to the pressure level of the pump (P-regeneration) or directly to the piston area respectively the A-port of the valve (A-regeneration). The Parker regenerative valves use the advantageous A-regeneration.
The hybrid version with an integrated solenoid valve can switch between regenerative mode and standard mode. The regenerative mode is used for maximum velocity, the standard mode for maximum force.
