Pilot Operated Pressure Reducing 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 pressure reducing valves provide stable pressure control with low pressure rise in applications where specific a specific pressure is needed for precise operation on functions that require regulated pressures up to 350 bar (5000 psi) and flows up to 150 lpm (40 gpm). Parker's pilot operated reducing valves are designed with several pressure and flow 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 functions such as brake releases, dual pressure circuits, pilot pressure control, and downstream pressure control on various types of machinery within the mobile and industrial markets.

Markets:
• Industrial
• Miscellaneous Manufacturing
• Miscellaneous Mobile

Features/Benefits:
• Spool design provides low hysteresis
• Low parasitic loss
