Product features

Pneumatic UPVC ball valve (double ball valve) is an anti-corrosion plastic ball valve used for various corrosive pipeline fluid media. The valve body is assembled and molded with UPVC (CPVC) injection parts, which has super corrosion resistance. The pneumatic UPVC ball valve controls the opening and closing of the valve through the air source pressure, which reduces the required manpower and time in terms of work efficiency and greatly improves the workload. Generally, the medium temperature used for pneumatic plastic ball valve should not be too high. According to the material, the temperature can be between - 40 ℃ and 180 ℃, and the working pressure should not exceed 1.6 mpa. Pneumatic plastic ball valve is also not suitable for pipes containing hard particle liquid, so as to avoid scratching the ball surface or causing leakage from the sealing surface.
Features of pneumatic UPVC ball valve:

1. The unique connection mode of the pneumatic double ball valve is particularly convenient for installation and disassembly, and the maintenance is simple and easy.
2. The valve is controlled by the air supply pressure of the pneumatic actuator, which not only saves time and labor, but also improves the safety of the use of the ball valve.
3. The pneumatic plastic ball valve body is light in weight, flexible in rotation, convenient in use, simple in matching and large in circulation capacity;
4. The pneumatic double free valve makes the material of the ball valve hygienic, non-toxic, sanitary, wear-resistant and corrosion resistant, making it more widely used

Principle of pneumatic UPVC ball valve:
The pneumatic actuators of pneumatic UPVC ball valves can be divided into double acting and single acting. Generally, if they are used to regulate the medium flow control, double acting pneumatic actuators are selected. The single acting actuator has the function of spring return, which can be divided into the normally closed type and the normally open type, that is, the valve is in the open or closed position. When the gas source is lost or an emergency fault occurs, the valve automatically returns to the open or closed state, which can be used in the dangerous conditions of transporting combustible gas or combustible liquid.
