Product features

The electric wafer butterfly valve controls the opening and closing of the valve by the power drive of the electric actuator. The electric wafer butterfly valve itself has no flange, and the valve body is relatively thin. It uses a group of bolts to pass through the bolt holes, clamp the butterfly valve between the flanges at both ends of the pipe, and then connect it with bolts, so it is especially suitable for the site with limited space Where the pipeline distance is relatively short. As the bolt of the electric wafer butterfly valve will expand under high temperature, which may lead to leakage, it is generally not recommended to use it under high temperature conditions.

Electric wafer type hard seal butterfly valve Electric wafer type soft seal butterfly valve

Application of electric wafer butterfly valve:
The electric wafer butterfly valve can be divided into hard seal and soft seal according to the different sealing materials. The soft seal butterfly valve is the central line type, which is generally used in places where the temperature and pressure are not very high or with corrosive media. It has the advantages of corrosion prevention and zero leakage. Metal hard seal butterfly valves are mostly double eccentric or triple eccentric, which are not only suitable for normal temperature and pressure situations, but also widely used in high-temperature and high-pressure working conditions. Moreover, the valve seat and disc plate do not rub, and have the advantages of long service life. The wafer type electric butterfly valve can quickly open and close the valve only by rotating 90 °. According to the different functional options and operating conditions of the electric actuator, it can be used as the control mode for opening and closing the valve, and can also be used to adjust the medium flow and pressure.

Instructions for installation of electric wafer butterfly valve:
 
The electric wafer butterfly valve cannot be used at the end of the pipeline and in the downstream where disassembly is required, because when the downstream flange is disassembled, the wafer valve will fall off, and in this case, an additional nipple must be made for disassembly. The flange butterfly valve does not have the upper problem, but the cost will be relatively high.
The purpose of clamp type electric butterfly valve and flange type butterfly valve is the same. They both regulate the fluid flow. Their difference lies in the installation form. When the pressure is too high, it is recommended to use the flange type butterfly valve. For dangerous fluids, it is also recommended to use the flange type butterfly valve.
