Electrical Lugged Butterfly Valve

When the transmission mechanism of the convex ear butterfly valve rotates, the bearing will drive the valve plate to rotate and convert the rotational motion into linear motion through the convex ear. In this way, it is possible to control the flow rate of the medium. When the valve plate is in the open state, the medium can pass through smoothly; When the valve plate is in the closed state, the medium cannot pass through.

Structural Features

  • Lugged Body Design: The valve body features threaded inserts (lugs) around its perimeter, allowing for secure and easy installation into the piping system. This design is particularly beneficial for end-of-line service and systems requiring frequent maintenance.
  • Electric Actuator: The electric actuator is mounted on the valve, providing automated control over the valve’s operation. This actuator can be controlled remotely, allowing for precise flow regulation and system integration.

Benefits of Using an Electric Actuator

  • Enhanced Control and Precision: The electric actuator allows for precise control over the valve’s position, enabling fine adjustments to the flow rate. This level of control is essential in processes where accurate flow regulation is critical, such as in chemical processing and water treatment.
  • Remote Operation and Monitoring: Electric actuators can be integrated into a control system, allowing operators to monitor and adjust the valve remotely. This capability is particularly valuable in large or hazardous environments where manual operation would be challenging or unsafe.
  • Automation and Efficiency: Automating the operation of lugged butterfly valves enhances overall system efficiency. Electric actuators can be programmed to operate the valve based on specific parameters, reducing the need for manual intervention and minimizing the risk of human error.
  • Improved Safety: By allowing remote operation, electric actuators reduce the need for personnel to be in potentially dangerous areas. This enhances safety, particularly in industries dealing with hazardous materials or extreme conditions.
  • Durability and Reliability: Modern electric actuators are designed for long-term reliability and can withstand harsh operating conditions. When combined with the robust design of a lugged butterfly valve, the result is a highly durable and dependable system component.

Applications

  • Chemical Processing: The precise control and remote operation capabilities are essential for maintaining accurate flow rates and ensuring safe operation in chemical processing plants.
  • Water and Wastewater Treatment: Electric lugged butterfly valves provide reliable and automated flow control, which is critical for efficient water and wastewater treatment processes.
  • HVAC Systems: These valves are used in heating, ventilation, and air conditioning systems to regulate air and fluid flow, contributing to system efficiency and energy savings.
  • Power Generation: In power plants, electric lugged butterfly valves are used to control cooling and process water flows, ensuring reliable and efficient operation.
