C400S uses a pipe mounting structure with a 1/4 inch port size. When the fluid pressure exceeds 0.35 bar, the valve opens to allow one-way flow. When the pressure drops, the valve closes to prevent reverse flow.

The steel valve body has high strength. The 316 stainless steel spring and 416 stainless steel poppet ensure reliable operation. The 1/4 inch NPTF threaded connection makes installation easy. C400S check valve is suitable for pipeline systems requiring 1/4 inch threaded port connection. The nitrile rubber seal also makes it suitable for low temperature applications.
