Pneumatic type regulator is oil, chemical industry, electric power, metallurgy, and other industrial enterprises the extensive use of industrial process control is one of the instrument. Usually by pneumatic actuators and regulator connection after installation of the formation of the combination instrument. Pneumatic-valve is to compressed air to power source, for in cylinder actuators, and by electric valves locator, converter, electromagnetic valve, the valve accessories to drive a valve, realize the switch quantity or proportion type adjustment, receiving industrial automatic control system of control signal to complete the adjustment of the medium pipeline: flow rate, pressure, temperature, etc. Various kinds of process parameters. The characteristics of the pneumatic-valve control is simple and quick response, and essential safety, do not need to take another explosion protection measures.

Pneumatic-valve by pneumatic actuators and regulatory valves two. Actuator is the implementation of the push device, which, in the compressed air is the power, export thrust; The regulator is the implementation of the regulation part, direct contact with the media, regulatory medium flow. The pneumatic-valve has simple structure, reliable operation, export thrust large maintenance convenient and inexpensive, such as fire blast merits pneumatic-valve widely used in chemical, petroleum, metallurgy, electric power, textile and other industrial production processes autopilot and remote control. Pneumatic-valve in nominal pressure and temperature range can adjust various kinds of liquid, gas and steam, pneumatic-valve closed less leakage. Pneumatic-valve actuator according to the functions of the gas or air can reach the purpose of open shut.
