Applications of WCB material
WCB material is one of the most widely used carbon steels in the industry. Carbon steel SA216 WCB is used not only in many of the water- and steam-pressure-containing systems in power plants but also in the supports for these systems. Carbon steel SA216 WCB is carbon steel suitable for fusion welding in high-temperature service applications: steel castings for valves, flanges, fittings, or other pressure-containing parts for high-temperature service and of a quality suitable for assembly with other castings or wrought steel parts by fusion welding.
Features of WCB Gate Valve:
The design of the body and bonnet joints of ZECO WCB gate valve requires an even load on the gasket to ensure a tight seal.1500 lb, including 1500 lb usually can use bolted bonnet structure, but 1500 lb of pressure seal structure is used;
The wedge of ZECO WCB gate valve has accurate guide slots, assuring true alignment and providing full guidance during operation. In this way, the gate sealing surface can be exactly matched with the valve seat sealing surface to maintain the zero leakage seal;
ZECO WCB gate valve is provided with a backseat bushing in the bonnet, enabling the replacement of the stem packing when the valve is in the wide open position. However, ZECO does not recommend users to replace the packing when the valve is under pressure, because after all, there is no professional guidance, which is easy to cause danger;
ZECO is a professional manufacturer of WCB gate valves. We have long-term strategic cooperation agreements with a number of foundry companies. Even if the order volume is large, ZECO can deliver the goods to users in a short time.
