Product Description


what is the Wafer Butterfly Valve with Tamper Switch ?What are the categories of Wafer Butterfly Valve with Tamper Switch?

Wafer butterfly valve with tamper switch is a butterfly valve equipped with a tamper switch for monitoring and control purposes. Butterfly valves are commonly used in industrial applications to regulate the flow of fluids in pipelines.

The wafer design refers to the valve’s slim profile, allowing it to be installed between flanges in a pipeline without the need for additional flange gaskets. This design is both space-saving and cost-effective.

A tamper switch is a feature that adds a control and monitoring element to a valve. It usually consists of a switching mechanism that triggers an electrical signal when the valve is tampered with or if there is any abnormality in its operation. This is useful for safety and security reasons as well as automation and integration with control systems.

In terms of category, wafer butterfly valves with tamper switches can be classified based on a number of factors:

Materials: Valves can be made from different materials, such as cast iron, stainless steel, or PVC, depending on the application and the type of fluid being handled.

Size: Valves come in various sizes to accommodate different pipe diameters.

End Connections: They can have different end connections such as wafer, lug or flange connections.

Operating mechanism: The valve can be operated manually using a handle or gear, or automatically using an electric or pneumatic actuator.

Tamper switch types: Tamper switches themselves can vary in design and technology, such as limit switches or proximity sensors.

When selecting a wafer butterfly valve with a tamper switch, factors such as fluid type, pressure, temperature, and the specific requirements of the application must be considered to select the best valve for the job.
