Reseat pressure 90% of crack pressure
Coil specifications Power requirements: 16 watts Magnet wire – UL class N rated (200º C)
Coil duty: Continuous from 85% to 110% of nominal voltage
(AC coils are internally rectified)
Temperature range -40° to 120° C (-40° to 248° F)
Fluids All general purpose hydraulic fluids such as:
MIL -H-5606, SAE 10, SAE 20, etc.
Operation
This standard valve package is
used to provide pressure line
relief for bi-directional motors
and cylinders. With the addi-
tion of a remotely controlled
shuttle valve, allowance is
made for motor slip or cylinder
dump conditions.
Features
Normally closed and normally
open options. Tamper proof
or adjustable relief options,
gauge port. Low power
requirements, number of volt-
ages and connectors options.
Aluminum in line type housing.
All components in the package
are true cartridges and can
be removed from the housing
without disturbing the plumbing.
