Brief instruction of DBB ball valve:

The key to the working principle of the double block and bleed and relief function valve is the action of the two sealing slides installed on the cock.

Double block and bleed and relief function valves are suitable for aviation kerosene, natural gas ,light oil , pipeline gas, liquefied gas, chemical media and other pipelines, as an ideal device for cutting off medias.

The valve has an automatic relief device (optional). After the valve is completely shut off, the valve cavity is prevented from abnormally increasing pressure and the effect of the valve is checked. The valve switch indicator is synchronized with the switch position, which can accurately display the switch status of the valve.

Other materials are available base on clients' requests.
