The C3220S uses a pipe mount structure with a #32 SAE port size. When the fluid pressure exceeds 0.35 bar, the valve opens to allow one-way flow; when the pressure drops below this value, the valve closes to prevent reverse flow.

The #32 SAE port thread provides a compact connection. The steel valve body has high strength. 316 stainless steel spring, 416 stainless steel poppet and nitrile rubber seal can ensure reliable long-term operation. The C3220S check valve is suitable for large diameter pipeline systems with #32 SAE port connection.
