DBB Plug Valve

1. During the valve opening and closing process, there is no contact between the valve body sealing surface and the sliding vane sealing surface. Therefore, there is no friction or wear on the sealing surface, the valve has a long service life, and the opening and closing torque is small;

2. When the valve is repaired, it is not necessary to remove the valve from the pipeline. You only need to remove the valve bottom cover and replace a pair of sliding vanes, which is very convenient for maintenance;

3. The valve body and the plug are full-bore, and the medium has no flow resistance when passing through the valve, and the pipeline can be cleaned, which overcomes the shortcomings of the reduced-diameter valve;

4. The inner cavity of the valve body is plated with hard chrome, and the sealing area is hard and smooth;

5. The elastic seal on the sliding vane is made of fluororubber and is molded in the groove on the surface of the sliding vane. The metal-to-metal seal with fireproof function serves as the backing of the elastic seal;

6. The valve has an automatic relief device (optional) to prevent abnormal pressure rise in the valve cavity and test the effect of the valve after the valve is fully closed;

7. The valve switch indicator is synchronized with the switch position to accurately display the switch status of the valve.
