Check Valve – C
The Polyhydron Check Valve C is a simple, high-pressure non-return valve that acts as a one-way street for hydraulic oil. It uses a spring-loaded “seat-type” design to ensure a tight, leak-free seal when flow tries to go the wrong way.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
The Check Valve – C is a seat-type valve that allows free flow from port A to port B while providing leak-proof closure in the reverse direction. It is available in both inline and sub-plate mounting options, conforming to factory and ISO standards for versatile installation.
