Parker Hannifin PRH102K10 - Pilot Operated Pressure Reducing Valves

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.
