Cast Steel Check Valve
Cast Steel Dual Plate Wafer Type Check Valve
Dual plate check valves - WCB, also known as cast steel, carbon steel. This steel has a good welding characteristic, suitable for use in the environment needs seat overlay welding.
TVCCL dual plate check valve with WCB material is America standard ASTM A216 WCB. Also be similar to material SCPH2. Carbon steel is an alloy of iron where the main alloying element is carbon. WCB material is most suitable for high-temperature use. The main advantage is the cost – Valve produced from carbon steels provide a cost-effective solution in environments where other factors are considered less important than cost. The disadvantage is poor corrosion resistance. This can be overcome by surface protection such as paint, provided that the line media does not corrode the valve from the inside.
