Gas liquid driving device is a driving device that uses gas pressure and liquid pressure to open, close or adjust the valve. It can meet the most demanding environment in the world (- 40 ℃ ~ + 85 ℃). Its electronic pipe breaking protection system overcomes the shortcomings of traditional products in terms of display and communication interface, and adopts the hardware manufacturing technology and process of aerospace and military industry to better meet the on-site use requirements of natural gas pipelines. It is the most effective and reliable angular stroke valve driving mechanism.
