Specification

DESCRIPTION
When the pressure at 'P' reaches the valve setting, the pilot spool initiates opening, followed by the main spool due to a pressure differential between its interior and exterior. This mechanism facilitates overflow from P to T. Our valve is engineered to endure a specific level of back pressure and features a rapid open/close rate, making it perfect for high-pressure and large-flow hydraulic systems.
