A solenoid-operated, 2-way, normally closed, poppet-type, bi-directional blocking, screw-in hydraulic cartridge valve for low leakage in load-holding applications.
When de-energized, the SV38-28 blocks flow in both directions, to pressure rating. If pressure on port 1 exceeds the rating, flow may pass from port 1 to port 2. When energized, the needle point lifts to open the valve biriectionally. Consult factory if used serially with orifice disc.
Operation of Manual Override Option: To override, push and hold override button.
• Continuous-duty rated coil.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Industry common cavity.
