WCB Globe Valve Class 150 Flanged End – Precision Flow Throttling & Reliable Shut-Off
Managing steam distribution, hydrocarbon streams, feed water, and general industrial process fluids requires durable, high-precision throttling valves capable of handling continuous pressure differentials. The WCB Globe Valve Class 150 Flanged End manufactured by FlowBiz Exports is engineered to provide linear flow regulation, tight shut-off, and minimum seat wear under demanding operational conditions.
Constructed from premium-grade cast carbon steel (ASTM A216 Gr. WCB), this Class 150 flanged globe valve incorporates an Outside Screw and Yoke (OS&Y) architecture with a rising stem and handwheel operation. Featuring a conical plug-type disc and hardfaced 13% Cr / Stellite seats, the FlowBiz WCB Globe Valve minimizes seat erosion during high-velocity throttling, ensuring long-term seat integrity across thermal power plants, refineries, and chemical processing complexes.
