PR10-32 Pressure Reducing/Relieving (PR10-32)
A screw-in, cartridge-style, direct-acting, spool-type, hydraulic pressure reducing/re-lieving valve with internal pilot and internal spring chamber drain, designed to act as a pressure-regulating device for secondary circuits. It is intended for use in stable input flow circuits.
Product Operation
In its steady state, the PR10-32 allows flow to pass bidirectionally from ➁ to ➀, with the spring chamber constantly drained at ➂On attainment of a pre-determined pressure at ➀, the cartridge shifts to restrict input flow at ➁, thereby regulating pressure at ➀. In this mode, the valve will also relieve ➀ to ➂ at approximately 10 bar (150 psi) over the reducing setting.Note: Direct-acting PR series valves may not be suitable for some static load
applications. Consult factory.
Product Features
• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Optional spring ranges to 145 bar (2100 psi).
• Hardened spool and cage for long life.
• Industry common cavity.
