DESCRIPTION
A solenoid-operated, 2-position, 3-way, bi-directional blocking, screw-in hydraulic directional cartridge valve designed for low leakage in load-holding applications.
OPERATION
When de-energized, the SV38-38 blocks flow between 2 and 3, while allowing flow between 2 and 1.
When energized, flow is allowed between 2 and 3, while flow is blocked between 2 and 1.
FEATURES
• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
