Electric knife gate valve
The Electric Knife Gate Valve is engineered for slurry, pulp, wastewater, and particle-laden fluids. Equipped with a high-performance electric actuator, it enables fast, accurate opening and closing. Its wear- and corrosion-resistant construction, combined with reliable sealing, ensures long service life, low maintenance, and dependable operation in mining, chemical, and water treatment industries.
Electric knife gate valve
Electric Knife Gate Valves integrate a sharp knife-edge gate with an electric actuator to provide automated on/off control in abrasive, fibrous, or viscous pipelines. Ideal for medium- to large-diameter valves, these valves reduce operating torque, prevent clogging, and ensure precise shut-off.
The robust construction offers excellent resistance to wear, corrosion, and erosion. The electric actuator supports remote operation, intelligent control, and integration with PLC, DCS, and SCADA industrial automation systems. Flanged, wafer, and lug connections allow versatile installation, while OEM customization supports material, actuator type, and valve configuration requirements.
