Detailed Product Description

DGV trunnion mounted ball valves are widely used in oil, nature gas pipeline and the industries of liquefied gas, coal gas, etc. as an open/close control element. The design of seat seal uses unique two-level soft seal and metal to metal seal to form triple sealing to ensure seal reliability with small open/close torque and easy operation. So it is safe and free of maintenance to use this series of ball valve. This type of valves has advantage of less weighted and cost effective. It is ideal for frequent on-off flow control in big size and high pressure pipeline
