Cast Steel Check Valve
Cast steel check valve opens automatically to allow forward flow in piping system, and automatically returns to its closed position to prevent reverse flow of fluid and protect the pump and its motor from being operated in reverse rotation.
The valve body is manufactured using casting process while the valve trims (internal parts) are specially treated to provide high strength and excellent corrosion and wear resistance. The cast steel check valve is featured by small size, light weight and good processability.
