electric ball valve and control valve of pneumatic ball Industrial Valves is self-control. They all is to achieve the final requirements of performance for the control of the ball valve. The power source of the electric ball valve from electric actuator motor. Pneumatic actuators and pneumatic ball valve power supply from compressed air.

the difference as well as the advantages and disadvantages:

1: price, generally expensive electric ball valve in pneumatic ball valve. But also points the single-acting pneumatic ball valve actuator and double-acting actuators, single-acting pneumatic actuators than double-acting actuators price expensive.

2: switch time: in general, pneumatic ball valve switch time is shorter, and the switching time of the electric ball valve is long. For example, the pneumatic ball valve can close in 10 seconds, in the more than 25 seconds, the fastest electric ball valves, but also has a fast on fast off the electric ball valve. Also can reduce the time.

3: stability, the stability of the electric ball valve pneumatic ball valve, as if the electric actuator for a long time use will appear a few problems, such as card phenomenon. And while a pneumatic ball valve performance is stable, high precision. But it needs more fixed gas source.

4: advantages and disadvantages of contrast:

electric ball valve advantages: the electric ball valve for liquid liquid medium, and large diameter pipe diameter gas effect comparison, because it is not influenced by environmental climate factors.

electric ball valve disadvantages: relatively expensive, the price is not high. Used in damp environment and affect the electric performance.

pneumatic ball Industrial Valves advantages: the pneumatic ball valve for liquid gas medium and small diameter effect is good, easy to maintain.

pneumatic ball valve disadvantages: the influence of air compressed air pressure fluctuations, winter in the north are susceptible to empty air water effect, cause transmission part to freeze, not action.
