Specification
DESCRIPTION
Our innovative valve design ensures optimal performance: when the pressure at 'P' meets the valve setting, the pilot spool initiates opening. Subsequently, the main spool opens, driven by the pressure differential between its internal and external environments, enabling seamless overflow from P to T. This valve type is engineered to endure considerable back pressure and boasts an exceptional opening and closing rate, making it ideal for high-pressure, high-flow hydraulic systems.
