Product Description

Overview of explosion-proof pneumatic ball valve
Explosion-proof pneumatic ball valve is composed of ball valve and equipped with explosion-proof solenoid valve and explosion-proof limit switch of pneumatic actuator connection, only need to input 0.4-0.7MPa of the air source to switch two valve operation. Pneumatic explosion-proof ball valve itself with fire, discharge electrostatic device (ball, stem, valve body is provided with a spring), there will be no contact with sparks, has good explosion-proof performance, widely used in steam, chemical, gas, oil products and other flammable and explosive conditions. According to the medium of the pipeline and different occasions, the assembly of different explosion-proof grades of solenoid valve and limit switch and other electrical control components.

Explosion-proof pneumatic ball valve principle of action
Pneumatic explosion-proof ball valve actuator according to different forms of action can be divided into single action and double action two, single action by spring automatic reset, its unique advantage is that once mechanical failure or through the air source, the ball valve will automatically located in the open or closed state. The double-acting switch action is driven by the air source; That is, air on, air off, air off to stay in place.
