Product Description


What is the Double Eccentric Grooved Butterfly Valve with Tamper Switch (XD382X) ?

The Double Eccentric Grooved Butterfly Valve with Tamper Switch, specifically the XD382X model, is a type of butterfly valve designed for use in piping systems. Let’s break down its key components and features:

Double Eccentric Design:

The term “double eccentric” refers to the offset positioning of the valve shaft and disc. This design reduces friction during operation and enhances sealing performance. As the disc rotates, it moves away from the seat in both an offset and an inclined manner, reducing wear and improving the sealing capabilities.
Grooved Connection:

The grooved connection indicates that the valve is designed for installation in grooved piping systems. Grooved connections involve joining pipe sections with grooved mechanical couplings, eliminating the need for welding or flanges.
Butterfly Valve:

The butterfly valve itself consists of a disc (or plate) mounted on a rotating shaft. The disc controls the flow of fluids by adjusting its position in the flow path.
Tamper Switch (XD382X):

The inclusion of a tamper switch adds a monitoring and control element to the valve. The tamper switch can detect unauthorized tampering or irregularities in the valve’s operation, providing an additional layer of security and control.
Key Features and Functions:
Sealing Performance: The double eccentric design enhances the valve’s sealing capabilities, minimizing the risk of leakage during operation.

Ease of Installation: The grooved connection simplifies installation, making it a cost-effective and efficient choice for certain piping systems.

Security and Control: The tamper switch offers a means of monitoring the valve’s status, providing feedback on potential issues and unauthorized access.

Reduced Wear and Friction: The double eccentric design reduces wear on the valve components, extending the valve’s lifespan and improving its overall performance.

Compatibility: The grooved butterfly valve with tamper switch is suitable for applications where grooved connections are preferred, and where additional monitoring and control features are necessary.

When considering the XD382X model for a specific application, it’s essential to evaluate the compatibility with your piping system, the type of fluid being handled, pressure and temperature conditions, and the level of security and control required in your system. Always refer to the manufacturer’s specifications for detailed information on the valve’s capabilities and installation guidelines.
