Operation
The valve allows flow from
port 2 to port 1 or from port
3 to port 4 when the spring
bias is overcome. Flow is
blocked from ports 4 to 3 and
from 1 to 2 until pilot pressure
is applied to ports 2 and 3
respectively.
Features
Hardened and ground poppets
to give minimal internal leak-
age and long life.

DPC2-8 - Check Valve
Dual, pilot-to-open, poppet type
19 L/min (5 USgpm) • 240 bar (3500 psi)
Description
This is a dual pilot-to-open
check valve ideal for stabilizer
cylinders fitting directly into
the cylinder reducing pipework
to a minimum.
A – Port 2 to Port 1
B – Port 3 to Port 4
WARNING
Do not use
Pilot-to-Open Check
Valves in load holding
applications where either
overrunning loads are
possible or load release
speed is critical. Failure to
observe these guidelines may
result in bodily injury or
damage to equipment.
