Specification

DESCRIPTION
Our advanced relief valves are engineered for precision and efficiency. When the pressure at port one hits the preset valve level, the pilot spool initiates its opening sequence, subsequently causing the main spool to engage due to the pressure differential between the interior and exterior of the main spool, thus achieving overflow from port one.

to port two. This initial pressure setting establishes the first level. When a specific pressure is applied to port three, the overflow pressure from port one to port two escalates, forming the secondary pressure setting.
