Pneumatic plug valve is an industrial valve mainly used to control the flow of fluids. Here are some key information about pneumatic plug valves:

working principle:
Pneumatic plug valve is mainly composed of components such as frame, gate, screw, nut, etc. It uses compressed air as a power source, changes the direction of the air path through solenoid valves, pushes the cylinder piston, and drives the gate to reciprocate horizontally to achieve the purpose of opening and closing the valve
The opening and closing actions of this valve are driven by a pneumatic actuator to complete the insertion plate, which can achieve rapid cutting and opening. 

Application scenarios:
Pneumatic plug valves have a wide range of applications in industrial and pipeline control fields. Some of the main application scenarios include natural gas pipeline control, chemical industry, water and sewage treatment, food and pharmaceutical industry, etc
They are particularly suitable for situations where rapid cutting off of pipeline fluids is required, protecting personnel safety, reducing accident risks, and improving industrial production efficiency.

Product features:
Pneumatic plug valve has the characteristics of simple structure, flexible operation, light weight, no jamming, and fast cutting off. They are particularly suitable for the transportation and flow regulation of various viscosity free solids, powders, and particles smaller than 10mm, as well as crystalline particles. Installation is not limited by angle, easy to operate, and the opening can be adjusted at any time.

Materials and specifications:
Pneumatic plug valves are typically manufactured using high-grade materials such as ASTM A351 CF8 and ASTM A351 CF8M to ensure durability and corrosion resistance. They have multiple sizes and pressure ratings to choose from, such as 4-inch DN100 and Class 150 LB ratings, as well as PN16 pressure rating.

Technical parameters:
The technical parameters of pneumatic plug valves include nominal pressure, shell testing, sealing testing, and operating temperature. For example, the working temperature of a rubber sealed pneumatic plug valve does not exceed 80 ℃, while a hard seal can reach 425 ℃.

Execution standards:
The design and manufacturing of pneumatic plug valves follow specific industry standards, such as JB/T8691-1998, GB/T15188.2-94, etc
