Metal Seated Lift Plug Valve, API 6D, A217 C5, 2 Inch, CL300

Product Name: Metal Seated Lift Plug Valve
Design Standard: API 6D, API 599
Body Material: ASTM A217 C5
Size: 2 Inch, DN50
Pressure: Class 300 LB, PN50
End Connection: RF Flanged
Operation: Handwheel

The Lifting Plug Valve operates by a two-step action for both opening and closing. When opening the valve, the handwheel is first turned to lift the plug, separating it from the sealing surface. Then, the handle is turned 90 degrees to align the plug channel with the valve body channel, allowing the valve to open. To close the valve, the handle is turned 90 degrees, making the plug channel perpendicular to the valve body channel, and the handwheel is turned to lower the plug, sealing the valve.
This design ensures a reliable and smooth operation, making the lifting plug valve an ideal choice for industries such as petroleum, chemical, pharmaceutical, fertilizer, and power. With KOSEN's dedicated workshops and advanced mold casting capabilities, you can be assured of high-quality performance for all your plug valve needs.

Working Principle of Lifting Plug Valve

The lifting plug valve consists of several key components: valve body, valve stem, valve cover, fixing device, positioning device, sealing device, blowing pipe, lifting screw sleeve, rotating handle, and others.
To operate, rotate the lifting screw sleeve clockwise to release the valve stem.
Next, rotate the upper rotating handle to move the valve stem, positioning it in the desired place.
Once in position, rotate the lifting screw sleeve counterclockwise to lock the valve stem, completing the valve's switch between open and closed states.
