Key Specifications / Features
The DBB ball valve is a double-closing, double-closing and relief function valve. Double shut-off and double-discharge and relief function valve, suitable for aviation kerosene, light oil, natural gas, liquefied gas, pipeline gas, chemical medium and other pipelines, as an ideal device to cut off the medium.

The key to the working principle of the double-closed double-break and bleed valve is the action of the two sealing slides installed on the cock.
The valve has an automatic relief device (optional). After the valve is completely closed, it prevents the valve chamber from abnormally increasing pressure and checks the effect of the valve. The valve switch indicator is synchronized with the switch position, which can accurately display the valve switching status.
