SV38-26 Valve

SV38-26 Valve symbol

A solenoid-operated, 2-way, normally closed, needle-type, direct-acting, screw-in hydraulic
cartridge valve, intended for blocking or load-holding in low flow circuits.

When de-energized, the SV38-26 blocks flow in both directions, to pressure rating. If pressure on
port 1 excees the reating, flow may pass from port 1 to port 2. When energized, the needle point
lifts to open the valve bidirectionally. Port 2 is the recommended load-holding port.
Operation of Manual Override Option: To override, push button in and twist counterclockwise 180°
and then release. In this position the valve will remain open. To return to normal operation, push button
in, twist clockwise 180°, and release. Override will be detented in this position.

• Double-blocking - can block flow in both directions.
• Relieving function from port 1 to 2.
• Hardened seat for long life and low leakage.
• Optional coil voltages and terminations.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Manual override option.
• Industry common cavity.
