Product details
Introduction to electric switch butterfly valve:
Electric switch butterfly valve is commonly known as electric double position cut-off butterfly valve, which is generally divided into two states: fully open and fully closed. The electric butterfly valve can achieve precise full open or full close and stop automatically under electronic control, and cannot directly interact with the flow feedback device of the pipeline system to adjust the flow rate accurately. According to the different connection methods, there are mainly flange type electric switch butterfly valves and clamp type electric switch butterfly valves. Different sealing structures (soft sealing structure and metal hard sealing structure) can be selected to correspond to different media, and are generally suitable for two position switch (quick cut-off) control occasions.

Characteristics of electric switch butterfly valve:
1. Electric switch butterfly valve relies on an electric actuator to control the opening or closing of the butterfly valve, with a voltage of AC220V (optional).
2. Relying on electricity to drive valves reduces manual labor and saves time and effort.
3. The switch is in place in a timely manner, the completion degree of the switch is good, and there is basically no error.
4. The electric actuator is equipped with a manual device, which can be manually operated in case of power outage or actuator failure to ensure normal working conditions.

Electric switch butterfly valve andElectric regulating butterfly valveThe difference:
1、 The opening and closing of the switch type electric butterfly valve only have two positions, either fully open or fully closed, and cannot be used for regulating and controlling the flow rate of the medium.
2、 The regulating electric butterfly valve can control the flow rate, pressure, temperature, etc. of the medium in the pipeline, and its three eccentric sealing valve core design can ensure resistance to erosion and gas corrosion in the semi open state.
