Item Number:

Double flange electric soft seal butterfly valve is a type of valve with a butterfly-shaped disk that rotates to control the flow of fluid. It is designed with two flanges that connect to the pipes on both sides of the valve, providing a secure seal. The valve is equipped with an electric actuator that remotely controls the opening and closing of the valve, making it ideal for automation and remote operation. The soft seating material ensures a tight seal, preventing leaks and reducing maintenance requirements.
