Product Description


what is the Grooved Butterfly Valve with Tamper Switch ?Grooved end and Wafer connect Butterfly valve,who is better ?

The choice between a Grooved Butterfly Valve with Tamper Switch and a Wafer Connection Butterfly Valve depends on the specific requirements of your application and the characteristics of your piping system. Let’s compare the two:

Grooved Butterfly Valve with Tamper Switch:
Grooved End:


Ease of Installation: Grooved connections simplify installation, as they eliminate the need for welding or flanges. This can result in faster and more cost-effective installation.
Flexibility: Grooved piping systems allow for flexibility in the alignment of pipes, making them suitable for certain applications.

System Compatibility: Ensure that your piping system is designed to accommodate grooved connections.
Tamper Switch:


Monitoring and Control: The tamper switch adds a layer of security and control by detecting unauthorized tampering or irregularities in valve operation. This is valuable for safety and system integrity.

Maintenance: Regular maintenance may be required for tamper switch components.
Wafer Connection Butterfly Valve:
Wafer Connect:

Space Efficiency: Wafer butterfly valves have a slim profile and can be installed between flanges without the need for additional gaskets. This saves space and reduces installation costs.
Lightweight: Wafer valves are often lightweight compared to other types.

Flange Compatibility: Ensure that your piping system has the appropriate flange connections for wafer valves.
Choosing Between the Two:
Application Specifics: Consider the specific requirements of your application, such as fluid type, pressure, and temperature conditions.

Space and Weight Constraints: If space efficiency and lightweight design are crucial, a wafer connection butterfly valve may be preferred.

Installation Ease: If quick and straightforward installation is a priority, the grooved butterfly valve might be more suitable.

Security and Control: If monitoring and control features are essential for your system’s safety, the tamper switch in the grooved butterfly valve may be a deciding factor.

In summary, both types have their advantages, and the choice depends on your specific needs and the characteristics of your piping system. It’s recommended to consult with valve suppliers or manufacturers to ensure that the chosen valve meets the requirements of your application.
