Introduction to the knowledge of imported electric wafer type butterfly valve

Electric valves and electric adjustments are among the varieties in the valve. The main connection methods are: flange type and clip type. It is an important execution unit in the field of industrial automation control.
This type of valve is generally installed horizontally.
Structure and working principle: It is usually composed of a quarter-turn electric actuator (0~90° partial rotation) and a butterfly valve as a whole through mechanical connection.
According to the action mode, there are: switch type and adjustment type.
The switch type is directly connected to the power supply (AC220V or other power supply level) through the switch forward and reverse steering to complete the switching action.
The adjustment type is powered by the AC220V power supply, and receives the preset parameter value of the industrial automation control system of 4~20mA (0~5 and other weak current control) signals to complete the adjustment action.

Main use: Control of pipeline flow, pressure and temperature in various industrial automation production.
For example: electricity, metallurgy, petrochemical, environmental protection, energy management, fire protection systems, etc.

Butterfly valve suitable for medium: fresh water, sewage, sea water, air, steam, food, medicine, various oils, acids, alkalis, salts, etc.
