The C420S uses a steel pipe body with a #6 SAE pipe thread connection. The valve opens when the fluid pressure exceeds 0.35 bar and closes when below this pressure.

The steel valve body is durable. The 316 stainless steel spring and soft seal poppet provide reliable performance. It can withstand a maximum working pressure of 207 bar, suitable for medium pressure systems. Using nitrile seals, the working temperature range is wide. The C420S check valve is suitable for #6 SAE size piping systems requiring corrosion resistance and high pressure handling capability.
