Specification

DESCRIPTION
This robust valve is engineered for high-pressure hydraulic systems. When the pressure at 'P' reaches the set threshold, the pilot spool initiates its opening, followed by the main spool due to the pressure differential. This mechanism facilitates the overflow from P to T. Designed to endure back pressure, this valve is characterized by its swift opening and closing rate, making it an ideal choice for systems demanding high pressure and large flow dynamics.
