Uses and characteristics:

Gas valves are widely used in urban gas supply network systems, such as gas, liquefied petroleum gas, natural gas, oxygen and other gas medium pipelines; The driving forms include manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.
