Description
The 10K/20K Cast Steel Swing Check Valve is a heavy-duty automatic valve designed to prevent backflow in piping systems. Constructed from durable WCB (SCPH2) cast steel, it is suitable for high-temperature and high-pressure services. The valve features a hinged disc that swings open for forward flow and closes against the seat to prevent reverse flow, protecting downstream equipment from damage.
