114 L/min (30 USgpm) • 350 bar (5000 psi)
Operation
This valve is used as a main
section of a pilot controlled
valve assembly. This valve has
multiple uses when used with
either directional control, flow
control or pressure control
cartridges. Refer to application
examples.
Features
Hardened and ground and
honed working components.
Cartridge construction for
maximum mounting flexibility.

Description
These are normally open or
closed logic elements with or
without a control orifice. They
can be used as main valves
for the control of high flows
using small pilot cartridges, as
compensators or load sense
elements.
