PR10-36 Valve

Patent Pending

SYMBOL:
PR10-36 Valve symbol

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 flow to pass bidirectionally from 2 to 1,
with the spring chamber constantly drained at 3. On attainment of a pre-determined
pressure at 1, the cartridge shifts to restrict input flow at 2, thereby regulating pressure
at 1. In this mode, 1 to 3 will be relieved. Deadband (from reducing to relieving) pressure
rise over reduced pressure setting: Non-flow condition: approximately 0.55 bar (8 psi);
With flow: 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 size.
