Natural gas pipeline ball valves
Natural gas ball valve adopts shaped PTFE packing, it is applied to most of the high and medium pressure gas transmission occasions, the handle operating torque is smooth, O-ring is used to prevent external impurities entering into the interior, and maintains a long-term sealing performance of the valve. The valve that is greater than DN150 uses worm gear drive.
