Specification

DESCRIPTION
Our meticulously engineered valve is designed to activate when the pressure at 'P' reaches the specified setting, initiating the pilot spool to open. Subsequently, the main spool engages due to the pressure differential around it, facilitating seamless overflow from 'P' to 'T'. This valve is adept at enduring back pressure, with an exceptional opening and closing rate, making it ideal for high-pressure, large-flow hydraulic systems.
