The explosion-proof pneumatic ball valve consists of a ball valve connected to a pneumatic actuator equipped with an explosion-proof solenoid valve and explosion-proof limit switches. It requires only a 0.4-0.7MPa air supply to perform two-position on/off valve operations.
The explosion-proof pneumatic ball valve incorporates built-in fire prevention and static discharge mechanisms (featuring springs between the ball, stem, and valve body), eliminating potential spark contact and ensuring reliable explosion protection. It is widely used in flammable and explosive environments such as steam, chemical processing, gas, and petroleum applications.
