According to pressure, it can be divided into high-pressure ball valve and low-pressure ball valve
High pressure pneumatic ball valve: mainly used in oil, natural gas, hydraulic oil, construction machinery and other industries
Low pressure pneumatic ball valve: mainly used in corrosive pipelines with water as the medium!

The pneumatic control valve uses the compressed gas as the power source, the cylinder as the actuator, and uses the valve positioner, converter, solenoid valve, retaining valve, gas tank, gas filter and other accessories to drive the valve, realize the on-off or proportional regulation, and receive the control signal from the industrial automation control system to complete the regulation of the pipeline medium: flow, pressure, temperature Various process parameters such as liquid level.
