FAQ
What is the operating principle of an electric knife gate valve?
An actuated knife gate valve operates using an electric actuator that converts electrical energy into mechanical motion. This mechanism moves the knife-shaped gate vertically to control the flow of media. The valve provides precise on-off functionality and integrates seamlessly into automated systems using a 4-20mA signal for feedback and control. It also includes protections against overloading and overheating to ensure reliable operation.
Which industries commonly use electric knife gate valves?
Electric actuator knife gate valves are ideal for industries that handle challenging media and require efficient flow control. Typical applications include wastewater treatment, chemical processing, mining, pulp and paper, food and beverage processing, and power generation. Their ability to manage abrasive, high-viscosity, and corrosive materials makes them a preferred choice in these sectors.
What types of mediums can an electric knife gate valve handle?
These valves are designed to handle a wide range of mediums, including abrasive slurries, high-viscosity fluids, solid-laden water, and corrosive chemicals. Depending on the chosen sealing material (STL, EPDM, PTFE, or VITON), the valve can operate effectively with both neutral and aggressive fluids.
What are the working conditions for electric actuated knife gate valve?
Electric actuated knife gate valve are built to withstand tough working conditions. They are suitable for both high and low-pressure environments, with durable construction materials like WCB, stainless steel (SS304, SS316, SS316L), and 310S ensuring resistance to wear and corrosion. The valve operates effectively within extreme temperature ranges and is compatible with AC220V, AC380V, and DC24V power supplies for flexible integration into diverse systems.
