Pneumatic ball valve overview and product characteristics
As the name implies, pneumatic ball valve is a ball valve driven by air. Because of its low fluid resistance, long service life and other advantages, often used in chemical, petroleum, paper and other industries. Let double pneumatic ball valve manufacturers for you to introduce the overview of pneumatic ball valve and product features!
Overview of pneumatic ball valve:
Pneumatic ball valve is a kind of pneumatic actuator widely used in modern automatic control system. Pneumatic actuator drives ball valve switch, control or adjust the medium switch in the pipeline.
The pneumatic ball valve is also equipped with a travel limit switch to realize the switching operation of the solenoid valve and send out two pairs of passive contact signals indicating the valve switch. The actuator is divided into two modes: single action and double action. The advantage of single function is once the power failure. It is automatically turned on or off according to the requirements of the control system. Widely used in chemical, refrigeration, paper and other industries. It can control not only gas, liquid and vapor media, but also sewage and fiber properties.

Pneumatic ball valve product characteristics:
(1) fluid resistance is small, pneumatic ball valve is one of the valves with small fluid resistance. Even for small diameter pneumatic ball valves, fluid resistance is small.
(2) Thrust bearing can reduce the friction torque of the valve stem. Make the stem run smoothly and flexibly for a long time.
(3) the seat sealing performance is good. Seals made of elastic materials such as teflon are easy to seal. As the medium pressure increases, the sealing capacity of the ball valve increases.
(4) The stem seal is reliable. Because the pneumatic ball valve stem only do up and down movement. Pneumatic ball valve rod packing seal is not easy to damage. As the pressure of the medium increases, the sealing capacity increases.
(5) Because of the good self-lubrication performance of PTFE material, the friction loss with the ball is small. Long service life.
