Operation
Pressure acts over one of two
differential areas forcing the pop-
pet back allowing relief flow to
the other port. This being a sin-
gle cartridge is ideal for mount-
ing on to a motor in a special
housing.
Pressure Drop
Cartridge only
Description
This is a direct acting bi-direc-
tional 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 a emer-
gency relief. Differential area,
fast acting, poppet valve.
