1CLLR100 - Dual Relief Valve
Poppet, direct acting differential area
150 L/min (40 USgpm) • 350 bar (5000 psi)
Description
This is a direct acting
bi-directional relief valve
designed to protect both
lines in a circuit from over
pressurization by relieving oil to
the other line. Ideal for use with
motors or directional valves as
an emergency relief. Differential
area, fast acting, poppet valve.
Operation
Pressure acts over one of two
differential areas forcing the
poppet back allowing relief flow
to the other port.
This being a single cartridge is
ideal for mounting on to a motor
in a special housing.
Features
Single cartridge relieving in
both directions cutting down
space requirements, giving full
adjustment through its range
on both pressures at the same
time.
