DAPR10-36 Pressure Reducing/Relieving（Pilot-Operated）

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 DAPR10-36 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, the valve will also relieve ① to ③ .
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.
● Hardened spool and cage for long life.
● Optional spring ranges to 207 bar（3000 psi）.
● Industry common cavity.
