Electric Actuated Ball Valve with Explosion Proof Actuator
The explosion proof electric ball valve is mainly composed of an explosion-proof actuator and a ball valve. It is a ball valve with explosion proof electric actuator specially designed for use in flammable and explosive conditions.The electrical components on the electric actuated ball valve explosion proof are required to be fireproof and anti-static, and all meet the explosion-proof standards. It can input the relevant power signal to control the valve opening and closing, input 4-20mA signal and 220V power supply to control the operation of the ball valve for proportional regulation.It has internal servo operation and opening signal position feedback, position indication, manual operation, simple connection and other functions.

- Explosion-proof electric ball valve refers that the explosion-proof electric actuator on the ball valve meet the standards of explosion protection. It is used in the occasion where explosion protection is required, such as liquid or gas, which is flammable and explosive in the chemical industry.
2.The main structure of the electric explosion proof ball valve is connected by explosion-proof electric actuator and valve, voltage AC220V or AC380V, can control the operation and on/off control of the valve.
- Ball valve with explosion proof electric actuator has two-way sealing and good sealing performance. The valve seat is generally made of PTFE. Since the valve ball is floating, under the action of the medium pressure, the ball can be displaced to the outlet end and pressed against the sealing surface at the outlet end, and the sealing force increases as the medium pressure increases.
4.The stem packing of explosion proof electric ball valve adopts V-type sealing structure. V-type packing can effectively convert the pressing force and medium force of the packing gland into the sealing force of the valve stem.
5.It can set anti-static structure according to customer requirements.There forms an electrostatic channel between the ball and the valve body by valve stem,so that the static electricity generated during the ball and valve seat switching process can be led to the ground through the valve body.It prevents risk of fire or explosion.
