Ball Check Valve
- The body is made of stainless steel 316L, using the ball sealing, high and low pressure sealing performance is good.
- It provides directional flow control and tight closure for high-quality liquids and gases. All check valves are equipped with check valve covers and rings, and check valves do not have absolute pressure holding function.
