PRESSURE CONTROLS
PR10-36 Pressure Reducing/Relieving, Pilot-Operated
USASI/ISO:
SYMBOLS
PERFORMANCE (Cartridge Only)
6.440.1
DESCRIPTION
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic pressure reducing/
relieving valve with internal pilot and internal spring chamber drain, designed to act
as a pressure-regulating device for secondary circuits.
OPERATION
In its steady state, the PR10-36 allows fl ow to pass bidirectionally from ➁ to ➀, with
the spring chamber constantly drained at
➂.
On attainment of a pre-determined pressure at
➀, the cartridge shifts to restrict input
fl ow at
➁, thereby regulating pressure at ➀. In this mode, the valve will also relieve
➀ to ➂.
Deadband (from reducing to relieving) pressure rise over reduced pressure setting:
Non-fl ow condition: approximately 0.55 bar (8 psi); with fl ow: approximately 2.1 bar
(30 psi).
FEATURES
• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Optional spring ranges to 207 bar (3000 psi).
• Hardened spool and cage for long life.
• Industry common cavity.
