Worm Gear Grooved Butterfly Valve Fire Signal Remote Control

The groove butterfly valve is connected by a groove machined at the end of the valve body and a corresponding groove at the end of the pipe, rather than a traditional flange or threaded connection. This design simplifies installation and allows for faster assembly and disassembly.

    grooved butterfly valves

    Grooved butterfly valves are beneficial in situations that require frequent maintenance or modifications, including HVAC (heating, ventilation, and air conditioning), fire protection systems, water treatment, and industrial processes.

    The worm gear groove butterfly valve adopts worm gear and worm drive. As the cam rotates, the contact on the signaling device is pressed down or released according to the predetermined position, and the "on" and "off" electrical signals are output accordingly to display the opening and closing status of the butterfly valve.

    The grooved butterfly valve has a simple structure and is easy to install. It is suitable for some occasions that require frequent operations.

    The grooved butterfly valve is flexible in operation and can be opened or closed quickly. It is suitable for some occasions that require quick response.

    A butterfly valve is a valve that can be used to isolate or regulate flow. The closing mechanism takes the form of a disc. The operation is similar to a ball valve, allowing for quick closure. Butterfly valves are often favored because they are lower cost and lighter than other valve designs, meaning less support is required. The valve disc is located in the center of the pipe, and through the valve disc is a stem that connects to the valve's external actuator. The rotary actuator rotates the valve disc either parallel or perpendicular to the fluid. Unlike ball valves, the disc is always present in the fluid, so there is always a pressure drop in the fluid regardless of valve position.
