The electric knife gate valve combines a wafer-type knife gate valve with an electric actuator. Its closing member is a gate plate, whose movement direction is perpendicular to the fluid flow. The medium is shut off by a knife-edge gate plate capable of cutting fibrous materials. The PZ973H electric knife gate valve utilizes an electric actuator powered by an external source to drive the gate plate in an upward or downward motion, thereby controlling the valve's opening and closing. When equipped with sensors or digital display devices, it enables remote computer-automated control. This valve is suitable for pipelines carrying media containing suspended particles or fibrous materials, such as pulp, sewage, coal slurry, and ash-cement mixtures.
