Specification

DESCRIPTION
Our advanced relief valve is engineered to perfection, activating when the pressure at "P" reaches the preset threshold. The pilot spool elegantly begins to open, followed by the main spool due to the meticulous pressure differential between its interior and exterior, allowing smooth overflow from P to T. Designed to withstand formidable back pressure, this valve boasts a rapid opening and closing rate, making it ideal for high-pressure, large-flow hydraulic systems.
