ANSI B16.34 Globe Valve, WCB, 2 Inch, CL150, Bellows Sealed

Product Name: ANSI B16.34 Bellows Sealed Globe Valve
Design Standard: ANSI B16.34
Body Material: ASTM A216 WCB
Size: 2 Inch, DN50
Pressure: Class 150 LB, PN20
End Connection: RF
Operation: Handwheel

The Bellows-Sealed Globe Valve incorporates advanced foreign technology and utilizes a double bellows design, welded to the valve stem, ensuring stable operating performance and preventing valve vibration caused by plug movement. At high temperatures, the stem remains isolated from the medium, ensuring zero leakage at the stem. The design also ensures sufficient strength and toughness, capable of withstanding tens of thousands of cycles. The ergonomically designed handwheel provides ease of operation, a longer service life, and greater convenience.
The bellows cut-off valve operates with a plug-shaped valve, and its seal face can be either flat or conical. The valve moves straight along the fluid's centerline. This type of valve is widely used due to its minimal friction between sealing surfaces during operation, enhancing durability. It features a small opening height, is easy to manufacture, and its dimensions are straightforward to design, contributing to its popularity and efficiency in various applications.
