The facility is further fortified with over 50 specialized measuring and testing devices. With an impressive annual production capacity exceeding 1 million hydraulic components, our diverse portfolio includes safety valves, overload valves, relief valves, balance valves, logic valves, solenoid valves, one-way valves, throttle valves, and pressure reducing valves. These components are indispensable in multi-way valves, gear pumps, steering systems, cylinders, and a myriad of hydraulic systems.

Specification

DESCRIPTION
Upon reaching the designated pressure at 'P', the pilot spool initiates its opening. This action triggers the main spool to open due to the pressure differential between the interior and exterior of the main spool, facilitating the overflow from P to T. This valve is engineered to endure significant back pressure while offering a swift opening and closing response. It is ideally suited for high-pressure and large-flow hydraulic systems.
