Product Name: DBB Twin Seal Orbit Plug Valve
Design Standard: API 6D
Body Material: ASTM A216 WCB
Size: 10 Inch, DN250
Pressure: Class 300 LB, PN50
End Connection: RF
When the twin seal orbit plug valve is fully open, the plug channel aligns with the valve body's channel, ensuring the ideal minimum pressure. Rotating the handwheel moves the plug towards the valve, causing the valve disc to rotate 90 degrees. As the handwheel continues to turn, the plug presses down, closing the valve tightly by pressing the valve disc against the valve seat. Rotating the handwheel in the opposite direction first lifts the plug, releasing the valve disc from the seat. Continuing to turn the handwheel rotates the valve disc 90 degrees, aligning the plug channel with the valve body channel, and the valve returns to its fully open position.

Product Features
This valve is designed with a strong structure, reliable sealing, great performance, and a sleek appearance. The sealing is achieved using rings around the valve disc, with extra protection from the wallow-tailed sink and fixed sealing rings. Its double-direction flow makes installation and use easier. The materials and flange sizes can be customized to match specific needs or customer requirements, making it suitable for various engineering applications.
