SV38-38 Double Blocking, 2 Position, 3-Way, N.C. (SV38-38)
A solenoid-operated, two-position, three-way, bi-directional blocking, screw-in hydraulic cartridge valve. It is designed for low leakage in load-holding applications.
Product Operation
When de-energized, the SV38-38 blocks flow from 3 to 2 or from 2 to 3.
When energized, flow is blocked from 2 to 1 or from 1 to 2.
Product Features
• Continuous-duty rated solenoid.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Optional waterproof E-Coils rated up to IP69K.
• Unitized, molded coil design.
• Industry-common cavity.
