Electric butterfly valve

Electric butterfly valve Product detail

Overview

This kind of product is assembled by the electric actuator of the soft sealing butterfly valve component. The soft sealing butterfly valve adopts the double eccentric structure valve plate, and the torque is small and the sealing is reliable during the opening or closing process. The electric actuator has two actions, which are suitable for the two-way adjustment of the process fluid. This kind of product can be widely used in metallurgy, electric power, petrochemical and other industrial sectors for fluid interception.
