Pneumatic actuated diaphragm type single-seated flow control valve

PNEUMATIC FLOW CONTROL VALVE

Pneumatic flow control valve, as the name suggests, is a valve that realizes flow regulation of fluid medium through pneumatic control. It is mainly composed of valve body, valve disc, seat, actuator and other parts. Its working principle is to change the flow rate of the medium by adjusting the opening of the valve, so as to achieve the control of the flow rate.

The working principle is mainly to control the opening of the valve through the actuator, so as to change the flow rate of the medium. The pneumatic actuator controls the valve opening through the air source.

1. High control accuracy

Pneumatic flow control valve is a kind of equipment to control the flow through the gas signal to control the valve opening. Compared with other forms of flow control equipment, pneumatic flow control valves have the advantages of high control accuracy and fast response speed. In the industrial automation control system, the accuracy and response speed of the unit operation are very important, and the accuracy and response speed of the pneumatic flow control valve can meet this requirement.

2. Convenient maintenance

The pneumatic flow control valve has simple structure and easy maintenance. Because the device mainly controls the valve opening through the gas, it is very convenient to maintain and replace the valve and the gas line. Compared with other control equipment, the maintenance of pneumatic flow control valves is relatively simple, which greatly reduces the cost of use.

3. Long service life

Long service life of pneumatic flow control valve. Because the equipment has few parts and simple design structure, its anti-loss performance and service life are much higher than other control equipment. After reasonable maintenance and maintenance, the service life of the pneumatic flow control valve can reach decades, which greatly reduces the cost of equipment replacement.

4. Wide range of application

Pneumatic flow control valve can be applied to a variety of media flow control, including gas, liquid, steam and so on. It is widely used in chemical industry, metallurgy, water treatment, food, medicine and other industries. Because of the reliability and adaptability of the pneumatic flow control valve, it has an irreplaceable role in different industries and different applications.

Pneumatic flow control valve is widely used in chemical industry, petroleum, electric power, metallurgy, pharmaceutical and other fields. In the chemical industry, pneumatic flow control valves are mainly used to control the flow of liquid, gas and other fluid media, and can accurately control the flow size. In the electric power, metallurgy and other industries, pneumatic flow control valves are mainly used to control the flow of pipes, containers and other equipment.
