What is the difference between electric ball valve and pneumatic ball valve?
1. Electric valve is powered by motor, and pneumatic valve is powered by compressed air.
(1) Advantages of electric valve:
It has good effect on liquid and large diameter gas, and is not affected by climate. Not affected by air pressure. Disadvantages: high cost, bad in humid environment.
(2) Advantages of pneumatic valve:
It has good effect on gaseous medium and small pipe diameter liquid, low cost and convenient maintenance. Disadvantages: Affected by the fluctuation of air pressure, it is very easy to be affected by the air pressure water in northern winter, which makes the transmission part freeze and remain motionless.
