This check valve has a steel pipe mounting structure with a #20 SAE port size. When the fluid pressure exceeds 0.35 bar, the valve opens and allows flow in one direction; when pressure drops below this level, the valve closes to prevent reverse flow.

The NPTF threaded connection allows for easy installation. The steel body provides high strength suitable for high pressure applications. The C2020S check valve has a compact structure suitable for piping systems. The 316 stainless steel spring, 416 stainless steel poppet and nitrile rubber seal can ensure reliable long-term operation under high pressure.
