High temperature electric welding ventilation butterfly pneumatic valve DN1000 images

Welding electric pneumatic valve is a kind of special high temperature and ventilation butterfly in high temperature gas, gas, dust, gas, flue gas and other occasions of pneumatic valves, pneumatic valve body with the same material processed into sealing ring, not only higher bracket with high temperature heat sink, protect the electric actuator using effect and service life, and the valve body between the butterfly plate and pneumatic expansion gap is big, can effectively prevent card deaths caused by heat from the cold.




welding type electric heat ventilation butterfly pneumatic valve for pressure is unfavorable and exorbitant, generally in 0. 6 - Within 1 mpa, pneumatic valve according to temperature, select material and can configure different electric actuators, such as switch, external regulation, explosion-proof, meet the requirements of a variety of different conditions using! If choose external regulation, can according to the input ( 4 - 20 ma signal) To achieve high temperature medium in pipeline according to the different flow of control signal to change its size, so as to realize the automation of industrial production engineering control and remote control.
