PCS13-12 - Pressure Compensator
Restrictive
58 L/min (15 USgpm) • 350 bar (5000 psi)
Description
This is a high pressure
restrictive style compensator
suitable for use with a
separate needle valve or
orifice to provide a pressure
compensated flow while
the excess oil passes over a
relief valve or closes down
the compensator on a pump.
This, when used in a manifold,
is ideal for motor or cylinder
speed control either meter in
or meter out.
Performance Data
Performance Characteristics
Cartridge Only
Operation
This valve, when used with
either a fixed or variable orifice
between port 1 and port 3,
maintains a constant flow. This
is based on what ever pressure
differential is chosen. Flow
out of port 2, regardless of
pressure, changes downstream
on port 2.
Features
Hardened and ground and
honed working components.
Cartridge construction for
maximum mounting flexibility.
Working pressure 350 bar.

(Customized housings are necessary
for close-coupling, compensator

5 Spool Seals
Blank - No seal on spool
S - Seal on spool.
(For load holding applications were
leakage from port 1 to 2 could cause
cylinder drift, use of seal will increase
hysteresis)
WARNING
Aluminum housings
can be used for
pressures up to 210
bar (3000 psi). Steel housings
must be used for operating
pressures above 210 bar
(3000 psi).
