DELCO Motorized valves Electric flange knife gate valves
The valve body of the electric knife gate valve adopts an integral design, with low fluid resistance and flexible and convenient operation. The screw drive of the valve adopts a double-plane bearing design, which greatly reduces the transmission friction and facilitates the opening and closing of the valve.
Motorized/Electric knife gate valves represent a pinnacle of innovation in fluid control technology, offering precise and reliable operation in a wide range of industrial applications. These valves are specifically designed to handle challenging fluids, slurries, and solids, making them indispensable in sectors such as mining, wastewater treatment, pulp and paper, and chemical processing.
In modern industrial processes, electric knife gate valves play a crucial role in optimizing process performance, enhancing productivity, and ensuring operational safety. Their ability to provide precise control, reliable operation, and remote control capability makes them indispensable in fluid handling systems across various industries.

Material: Stainless Steel 304/316 , Cast Iron
Description
Electric knife gate valves feature a robust and compact design optimized for efficient fluid control. The valve body typically consists of corrosion-resistant materials such as stainless steel or cast iron, ensuring durability and longevity in harsh operating environments. Within the valve body, a sharp-edged gate or blade is actuated by an electric motor, which allows for precise control of the flow path.
The electric actuator is the heart of the electric knife gate valve, providing the motive force to open and close the valve gate. It is powered by electricity and controlled by a programmable logic controller (PLC), a distributed control system (DCS), or other automation systems. Electric actuation offers several advantages, including precise positioning, remote control capability, and integration with advanced control strategies.
In conclusion, electric knife gate valves represent a cornerstone of fluid control technology, offering unmatched precision, reliability, and versatility in industrial applications. Their innovative design, electric actuation, and numerous advantages make them an indispensable component in fluid handling systems, ensuring optimal performance and efficiency in diverse industrial processes.
Electric Knife Gate Valve is a unidirectional wafer knife edge gate valve used on industrial pipeline for on-off operation.
The structure of body and seat eliminates clogging shutoff for flow with fine particles. Additionally, beveled knife edge helps the gate cut through thick media easily. According to different working situation: non-rising stem knife gate valve, wafer knife gate valve, lugged knife gate valve, pneumatic knife gate valve, electric knife gate valve, manual knife gate valve and bevel gear knife gate valve are all available.
