Microfinish Bellow Sealed Globe Valves: Microfinish Bellow Sealed Globe Valves are designed to ASME B16.34 and consist of both standard and Y-Type construction. They are available in 150 to 2500 ASME pressure classes in sizes ranging from inches to 12 inches with flanged or weld end connections. The valve utilizes a welded bellows design and is suitable for difficult applications where leakage to the atmosphere cannot be tolerated. . These valves are used for flow control, on/off isolation of fluids. Valve operation options include manual gear, pneumatic and electric actuation.
