The C620S uses a steel body with #6 SAE port connection. It opens when the fluid pressure exceeds 0.35 bar and closes when below this pressure.

The steel body provides good strength. The 316 stainless steel spring and soft seal poppet can provide reliable sealing at higher pressures. With a maximum working pressure of 207 bar, it is suitable for working in the temperature range of -40°C to +121°C.

The C620S check valve is suitable for piping systems requiring port size of #6 SAE and operating at pressures up to 207 bar, such as hydraulic and industrial applications. The nitrile seal also makes it suitable for oil applications.
