Explosion Proof Electric Ball Valve is an electric actuated 3-way ball valve for use in flammable and explosive occasions. It has the advantage of easy operation, large circulation capacity, simple structure and reliable performance. It uses a 380V or 220V power supply to control the opening and closing of the ball valve, and the electrical regulating type (4-20mA analog signal).
The explosion proof ball valve has an L-port or T-port, which can connect two channels perpendicularly, or change the direction of the flow. It can also be used to control the diversion or convergent of the medium.
There are many standards that classify equipment for use in hazardous environments. Some of the most important are NEMA (National Electrical Manufacturers Association), IEC Ex (International Electrotechnical Commission – Ex) and ATEX (ATmospheres EXplosibles – AT). These classifications relate to the environment where the device will be used, the gases or particulates in that atmosphere, and the level of protection required.
Unlike other types of actuators, electric explosion proof ball valves have no moving parts and so are less likely to spark. This makes them safe to use in explosive environments, such as mines or oil refineries. They are also more durable and less prone to damage, making them suitable for a variety of applications, including chemical dosing and flow management. The explosion-proof electric ball valves are also very easy to install and can be wired in parallel. This saves time and effort in maintenance and reduces labor costs.
