Handle signal groove butterfly valve

    The handle signal groove butterfly valve is a valve product that combines traditional butterfly valves and modern sensor technology. It is mainly used to control the flow of media in various pipeline systems, including fire pipe, HDPE water supply pipe, pvc drainage pipe and HDPE drainage pipe. At the same time, it can provide signal feedback on valve status. This type of butterfly valve is usually installed on fire protection systems or other pipelines that require remote monitoring of valve opening and closing status, in order to timely understand the opening and closing status of the valve and ensure the normal operation and safety of the system.

Structural characteristics
The structure design of the handle signal groove butterfly valve is compact and easy to operate, usually driven by the handle or worm gear, which can achieve rapid opening and closing. Its main components include valve body, valve plate, sealing ring, valve stem, and signal device. The valve body is usually made of ductile iron material, which has good mechanical strength and corrosion resistance. Valve plates are often made of stainless steel structure and then coated with glue to improve sealing performance. The signal device is responsible for converting the opening and closing status of the valve into an electrical signal and transmitting it to the control system.

Maintenance suggestions
1. Regularly check the sealing performance of butterfly valves to ensure that there are no leaks.
2. For butterfly valves that have not been used for a long time, they should be stored in a dry environment and the valve plate should be kept slightly open by 4 ° to 5 °.
If the butterfly valve is used for special media such as granular materials, special attention should be paid to the selection to extend the service life of the valve.

In short, the handle signal groove butterfly valve plays an important role in many industries with its unique signal feedback function. The ease of installation and maintenance makes it an important component in modern pipeline systems.
