Electric gate valve selection criteria:
Usually choose electric gate valve, the caliber is relatively large. Such as DN250 and above. Why do you say that?
1: Whether you are used underground or on the ground, manual operation is not recommended, because the hand wheel is really difficult to turn if manual operation is taken.
2: Because of the overall cost-effective advantage of the valve, compared with the ordinary manual gate valve and the electric gate valve, you will find that the price difference between them will be very large, as long as the price difference is because of the above of the electric actuator.
3: If the caliber is not very large, why choose the electric gate valve. That is because of the engineering pipeline required by the unit, the existence of such automation requirements for gate valves can meet the specific needs of customers for working conditions. Electric operation is simple and human words, do not have to manually open and close the valve, as long as the power switch can be used, you can also achieve remote control, is convenient, but the cost of electric actuators is relatively high, many customers can not accept.
