Specification

DESCRIPTION
When the pressure at 'P' reaches the pre-determined valve setting, the pilot spool initiates its opening sequence. This action subsequently prompts the main spool to open due to a pressure differential across it, facilitating fluid overflow from P to T. This valve is characterized by its rapid opening and closing capabilities and boasts minimal internal leakage, making it ideal for high-pressure, large-flow hydraulic systems.
