Pilot Operated Pressure Reducing Relieving Valves

Picture for category Pilot Operated Pressure Reducing Relieving Valves

*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 family of pilot operated acting reducing & relieving valves provide superior pressure control in applications where specific regulated and relief pressures are needed for precise operation on functions that require regulated pressures up to 380 bar (5500 psi) and flows up to 150 lpm (40 gpm). Parker's pilot operated acting reducing & relieving valves are designed with several pressure ranges in order to give a higher degree of control with a variety of adjustment style options available. The additional valve stability due to the pilot operation make these valves ideal for sensitive functions such as up or downforce, clamping, or braking applications on various types of machinery within the mobile and industrial markets.

Markets:
• Agriculture
• Construction Equipment
• Industrial
• Miscellaneous Manufacturing
• Miscellaneous Mobile

Features/Benefits:
• Multiple pressure ranges available for more accurate pressure control
• Compact size for reduced space requirements
• Adjustable and tamperproof versions available
• High pressure capacity
• All external parts zinc plated

Applications:
• Brakes
• Clamps
• Suspension systems
• Up/down-force systems

Additional Technical Insight:
Typical applications are in mobile & industrial equipment, where a branch of the system is intended to operate at a lower setting than high system pressure.  Hydraulic functions such as brake circuits, clamping or clutch circuits, suspension systems, street sweepers, or seeding and planting rows in agricultural equipment are common applications for these products.
