DBB ORBIT Twin Seal Plug Valve

Main Advantages

1. No friction of the sealing surface between the seat and vane,  thus the valve has extremely low torque and longer service life time.

2. Online maintenance, don’t have to remove the valve from the pipeline,  just open the bottom cover to replace the parts.

3.  Automatic cavity relief device. When the body cavity pressure rises, it will force the check valve open so to release the pressure to the downstream.
