Operation
With a pilot valve fitted the
valve will only open when flow
is allowed across the orifice in
the middle of the spool. Flow
passing across this orifice will
cause there to be a pressure
difference that acts over the
full area of the spool to move
it back against the spring that
biases it closed. By control-
ling the pressure in the spring
chamber you can control the
pressure at which the valve
opens.
Features
Very versatile in its application
using hardened and ground
spool and sleeve giving minimal
internal leakage and long life.
High flow and pressure rating
increases the variety of applica-
tions into which it can fit.

Sectional View
Description
For use in conjunction with
pilot valves to allow control
of larger flows. When used
with a 2/2 solenoid valve the
combination allows control of
flows to 350 lts/min (95 US
gpm). With a pilot relief valve
or a proportional relief valve
the element becomes a high
flow pilot style relief. With a
needle valve an on/off function
is achieved. The outlet flow
would normally go to tank
because back pressure will
act on the pilot cartridge to
increase the switching pres-
sure.
