Dual Expanding Plug Valve, A216 WCB, API 6D, 16 Inch, CL900

Key Specifications / Features

The Dual Expanding Plug Valve is designed according to API 6D and API 599 standards, featuring an ASTM A216 WCB body for strength and durability. With a 16-inch (DN400) size, it is rated for Class 900 LB and PN150 pressure classes. The valve includes RTJ flanged ends for secure, leak-proof connections, making it a reliable choice for high-pressure applications.

When the twin seal orbit valve is fully open, the plug channel aligns with the valve body channel, ensuring the ideal minimum pressure. Turning the handwheel moves the plug towards the valve, causing the valve disc to rotate 90 degrees. As the handwheel continues to rotate, the plug is pressed down, sealing both sides of the valve, and pressing the valve disc tightly against the valve seat, thereby closing the valve. Rotating the handwheel in the opposite direction first lifts the plug, releasing the valve disc from the seat. Continued rotation drives the plug to rotate the valve disc 90 degrees, aligning the plug channel with the valve body channel, fully opening the valve.
