ANSI 150LB Stainless Steel Flanged Globe Valve

1.The ANSI 150LB Stainless Steel Flanged Globe Valve adopts a rising stem disc design. Its disc and seat sealing surfaces are precision-ground or overlay-welded with Stellite alloy, delivering excellent sealing performance and enabling effective medium flow regulation during on-off operations. The valve stem is available in outside screw & yoke (OS&Y) or non-rising stem designs to prevent medium leakage, making it suitable for working conditions involving high pressure and high-purity media.

2.Valve Body Machining: The flange faces, sealing surfaces and mid-flange connecting faces of the ANSI flanged globe valve are precision-turned and ground by CNC machine tools, ensuring a tight sealing fit with pipeline flanges and complying with the ANSI B16.5 flange standard.

3.Valve Stem Machining: The valve stem of the ANSI 150LB Stainless Steel Flanged Globe Valve  is made of high-strength stainless steel bar stock through turning, quenching and tempering heat treatment, and thread machining processes. Its surface is subjected to nitriding or chrome plating treatment to enhance corrosion and wear resistance, adapting to long-term on-off operations under high-pressure working conditions.

Q:What are the core advantages of stainless steel flange globe valve compared with gate valve and ball valve?

A: The 150LB stainless steel flange globe valve is specialized in throttling and flow control, which is its biggest advantage. Compared with gate valves, it has precise flow regulation performance and better sealing tightness; compared with ball valves, it is more suitable for occasions requiring stable throttling under medium and low pressure. Combined with the corrosion resistance of 304/316L stainless steel, it is widely used in petrochemical, power plant and precision fluid control systems.

Q:What is the flow direction requirement for 150LB stainless steel flange globe valve during installation?

A: It has strict flow direction requirements and must be installed in accordance with the "low in and high out" direction marked on the valve body. This design ensures that the valve disc is pressed tightly against the valve seat under the action of medium pressure, improving sealing performance. If installed in reverse, it will not only reduce throttling accuracy and sealing effect, but also increase operation torque and even cause valve damage under high pressure.
