DBB Ball Valve

DBB ball valve is also called double bleed and block ball valve. Double-bleed, double-cut and venting function valve, suitable for aviation kerosene, light oil, natural gas, liquefied gas, pipeline gas, chemical medium and other pipelines, as an ideal device for cutting off the medium. The key to the working principle of the double bleed and double block 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, the valve cavity is prevented from being abnormally pressurized 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.
