PRODUCT OVERVIEW

Pneumatic globe valve with linear motion

I. Working Principle
The linear pneumatic globe valve mainly relies on compressed air as the power source. Through the pneumatic actuator, the valve stem is pushed to make a linear motion, thereby realizing the opening and closing of the valve. When compressed air enters the pneumatic actuator, it pushes the piston or diaphragm to move, and then drives the valve stem to move up and down, causing the valve to open or close.

II. Features
1. Fast response: Due to pneumatic driving, the response speed is fast. It can open and close the valve within a short time, which is suitable for occasions with high time requirements.
2. High control accuracy: The opening of the valve can be precisely controlled by adjusting the inlet pressure and flow of the pneumatic actuator, realizing precise regulation of the fluid flow.
3. High reliability: It has a simple structure, reliable action, is not prone to failures, and has low maintenance costs.
4. Strong corrosion resistance: Appropriate materials can be selected according to different working media, and it has good corrosion resistance.
5. Good sealing performance: High-quality sealing materials are used, which can effectively prevent medium leakage.

III. Application Fields
1. Petrochemical industry: It is used to control the flow and pressure of various chemical media, such as oil products, natural gas, chemical raw materials, etc.
2. Electric power industry: In power plants, it is used to control the flow and pressure of media such as steam and water.
3. Metallurgical industry: It is used to control high-temperature and high-pressure metallurgical media, such as molten steel and molten iron.
4. Water supply and drainage industry: It is used in urban water supply and drainage systems to control the on-off of water flow.
5. Other industries: It is also widely used in industries such as pharmaceuticals, food, and papermaking.​
