Trunnion mounted ball valve is widely used in oil ,nature gas pipeline and 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/colse torque and easy operation,so it is safe and free of maintenance to use this series of ball valve.This type of valve has advantage of less weighted and cost effctive.it is ideal for frequent on-off flow control in big size and high pressure pipeline.
