Electric pneumatic valve and manual ventilation ventilation air valve on the performance of what's the difference?

Electric pneumatic valve ventilation structure is compact, light weight, easy installation, small flow resistance, big circulation, avoid high temperature expansion effect, convenient operation. The body without connecting rod, bolts, etc. , reliable operation, long service life. Can transfer installation, is not affected by flow medium, it is adopted the midline type disc plate and short structure is a new type of structure design and manufacture of steel plate welding.

here let me tell you something about manual ventilation pneumatic valve and electric ventilation pneumatic valve performance difference!

a pneumatic valve, manual ventilation by plates welded together, a short structure size, light weight, easy installation, the pneumatic valve drive torque is small, easy, easy to operate. Pneumatic valve body is equipped with oil seal, seal no obvious gap between small leakage rate. The expansion of the gap between plate and pneumatic valve body is bigger, can effectively prevent heat expansion and cold contraction caused by congestion. The pneumatic valves can be equipped with all kinds of driving devices, such as device manual, worm gear drive, pneumatic, electric actuator, etc. Ventilation pneumatic valve is widely used in gold, chemical industry, electric power, building materials, mining and other industrial control or regulation on medium gas in the pipeline. Manual ventilation short pneumatic valve is a kind of structure, light weight, easy installation of industrial products. Manual ventilation and main parameters of pneumatic valve: nominal pressure ( MPA) : 0. 5 mpa, medium temperature: - 30℃～- 350 ℃, the strength test: 0. 1 mpa, suitable medium: hot and cold air, flue gas, the medium flow: 25 m/S leakage rate: 3%

manual ventilation pneumatic valve key features:

1, the reasonable design, compact structure, light weight, quick opening and closing.

2, torque is small, easy to operate, saving smart.

3, should use the right material, in order to meet the high, medium and low medium temperature and corrosive medium.

2, electric ventilation pneumatic valve has simple structure, small volume, light weight, low material consumption, small installation size, quick switch, 90 ° reciprocating rotation, and the characteristics of small drive moment, for cut off, the connection and regulate medium in pipe has good flow control characteristics and seal sealing performance, suitable for flue gas, dust, air or fluid containing suspended particles, and the turbidity and slurry flow regulation and control.

1, the working principle of the electric pneumatic valve ventilation: electric pneumatic valve ventilation from the Angle of electric actuators and ventilation pneumatic valve body. Electromechanical integration within the structure design of servo operation, break-brake position feedback signal, position indicator, the function such as manual operation, powerful, reliable in performance, reliable control. Powered by the AC220V or AC380V voltage, receiving input control system ( 4 - Ma or 1-20 5伏直流电) Current or voltage signal, so as to control operation.

2, electric ventilation characteristics of pneumatic valve:

1) The pneumatic valve drive torque is small, easy, easy to operate.

　　2) Can effectively prevent heat bilges cold shrink caused by congestion.

　　3) A short structure size, light weight, easy installation, etc.

　　4) USES the steel plate welding and become, a short structure size, light weight, easy installation, etc.

　　5) Aerodynamic body is equipped with the seal ring. No visible gap between vice sealing, small leakage rate.
