PCS14-12 - Pressure Compensator
Bypass or priority
58 L/min (15 USgpm) 350 bar (5000 psi)
Description
This is a high pressure priority
style compensator suitable for
use with a separate needle
valve or orifice to provide a
priority pressure compensated
flow. This when used in a
manifold is ideal for motor or
cylinder control where priority
is required.
Performance Data
Performance Characteristics
Cartridge only
Operation
This valve, when used with
either a fixed or variable orifice
on port 4, maintains a constant
flow out of port 3, regardless of
pressure changes downstream
of port 3. This is based on
whatever pressure differential is
chosen. All flow in excess of the
priority requirement is bypassed
from port 1 to port 2. If the
priority port is deadheaded, the
valve will try to direct flow out
of the priority port and shut off
the bypass flow, blocking of all
flow.
Features
Hardened and ground and
honed working components.
Cartridge construction for
maximum mounting flexibility.
Working pressure 350 bar.
