1 Description
This valve is a screw in cartridge type, guided poppet, hy
draulic check valve. Use as a blocking or load holding de
vice for 5000 psi (350 bar) applications. All external parts of
the cartridge are zinc plated to DIN 50�979 and are thus sui
table for use in the harshest operating environments. If you
intend to manufacture your own cavities or are designing a
line-mounting installation, please refer to the section “Rela
ted data sheets”.

6 Installation information
IMPORTANT!
When fitting the cartridges, use the specified tigh
tening torque. No adjustments are necessary,
since the cartridges are set in the factory.
ATTENTION!
Only qualified personnel with mechanical skills
may carry out any maintenance work. Generally,
the only work that should ever be undertaken is to
check, and possibly replace, the seals. When
changing seals, oil or grease the new seals tho
roughly before fitting them.

1 Description
The PDCV08… series dual pilot operated check valve
cartridges are size SAE 08 / NG 5, high performance
screwin valves with a 3/416 UNF mounting thread. This
unit is a cartridge type, high strength steel guided poppet for
realizable low leakage performance, dual hydraulic pilot
operated check valve, for use as a blocking or load holding
device at high pressure applications.This valve allows free
flow from port 2 to port 1 and from port 3 to port 4 and it
blocks flow from port 1 to port 2 and from port 4 to port 3.
Flow is allowed from port 1 to port 2 when pilot pressure is
sensed at port 3 or flow is allowed from port 4 to port 3 when
pilot pressure is sensed at port 2. In order to pilot the valve
opens, the pressure at port 2 or port 3 needs to exceed one-
third of the load pressure from port 1 or port 4. All external
parts of the cartridge are zinc-nickel plated to DIN 50�979
and are thus suitable for use in the harshest operating envi
ronments. If you intend to manufacture your own cavities or
are designing a line-mounting installation, please refer to
the section “Related data sheets”.

Important:
When fitting the cartridges, use the specified
tightening torque. No adjustments are necessary,
since the cartriges are set in the factory.
ATTENTION!
Only qualified personnel with mechanical skills
may carry out any maintenance work. Generally,
the only work that should ever be undertaken is to
check, and possibly replace, the seals. When
changing seals, oil or grease the new seals tho
roughly before fitting them.
