DESCRIPTION

A solenoid-operated, 2-way, normally open, poppet-type, screw-in hydraulic cartridge

valve, designed to function as a load holding or blocking valve in applications requir-

ing low internal leakage at high pressure.

OPERATION

When de-energized, the SF08-23 poppet lifts to open from ➁ to ➀. In this mode, ﬂ ow

is also allowed from

➀ to ➁.

When energized, the cartridge acts as a check valve, blocking ﬂ ow from

➁ to ➀ after

overcoming the solenoid force (requires 3.4 to 10.3 bar / 50 to 150 psi).

Operation of Manual Override Option: To override, push and hold override button.

FEATURES

• Continuous-duty rated solenoid.

• Hardened seat for long life and low leakage.

• Optional coil voltages and terminations.

• Efﬁ cient wet-armature construction.

• Cartridges are voltage interchangeable.

• Unitized, molded coil design.

• Manual override option.

• Optional waterproof E-Coils rated up to IP69K.

• Industry common cavity.
