Flange Ball Valves
ANSI 150LB Stainless Steel Flanged Ball Valve
Shangtai ANSI 150LB Stainless Steel Flanged Ball Valve is strictly designed and manufactured per ANSI B16.34 and API 608 standards. Featured with an anti-blowout stem and professional anti-static structure, it effectively prevents stem ejection under overpressure and eliminates static spark risks.
An ANSI 150LB Stainless Steel Flanged Ball Valve is a stainless steel ball valve with flanged end connections, designed for piping systems using the ASME Class 150 pressure class. It uses a quarter-turn rotating ball to start or stop the flow of compatible fluids and is commonly used for on/off isolation in industrial piping systems.
ANSI 150LB refers to the ASME Class 150 pressure class. The actual allowable working pressure depends on the valve size, material, operating temperature and applicable pressure-temperature rating. Stainless steel construction provides a corrosion-resistant valve body and can be specified with materials such as 304 or 316 stainless steel according to the application.
The flanged connection allows the valve to be bolted directly to matching pipeline flanges, providing a practical connection method for industrial piping systems and facilitating future inspection or maintenance. The ball valve mechanism provides quick quarter-turn operation for opening and closing the pipeline.
