SV08-26 Blocking/Low Flow, 2-Way, Normally Closed (SV08-26)
A solenoid-operated, two-way, normally closed, direct-acting, needle-type, screw-in hydraulic cartridge valve, designed to function as a blocking or load-holding device for low flow circuits.
Product Operation
When de-energized, the SV08-26 blocks flow in both directions, to pressure rating.
If pressure on ➀ exceeds the rating, flow may pass from ➀ to ➁When energized, the needle point lifts to open the valve bidirectionally. Port ➁ is the recommended load-holding port.
Operation of Manual Override Option: To override, push button in, twist counter-
clockwise 180° and 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.
