Product Description


what is the Grooved Butterfly Valve with Tamper Switch (XD381X)(GD-381X) ?What is the function of Grooved Butterfly Valve with Tamper Switch (XD381X) (GD-381X)? What are his connection standards?

The Grooved Butterfly Valve with Tamper Switch, specifically the XD381X (or GD-381X), is a type of butterfly valve designed for use in piping systems. Let’s break down its components and functions:
1. Grooved Butterfly Valve:
Butterfly Valve Design: Like other butterfly valves, it consists of a disc (or plate) mounted on a rotating shaft. The disc is positioned in the flow path and can be rotated to control the flow of fluids in the pipeline.
Grooved Design: The grooved butterfly valve typically features a grooved body, which allows for easy installation in grooved piping systems. This design eliminates the need for traditional flanges and gaskets.

2. Tamper Switch (XD381X or GD-381X):
Tamper Switch Integration: The XD381X model includes a tamper switch, providing a monitoring and control element to the valve.
Function: The tamper switch serves to detect any unauthorized tampering with the valve or any irregularities in its operation. This can be crucial for ensuring the security and integrity of the piping system.

3. Connection Standards:
Grooved Connection: The valve is designed for grooved piping systems. Grooved connections involve joining pipe sections with grooved mechanical couplings, eliminating the need for welding or flanges.
Connection Standards: The specific connection standards for the XD381X (GD-381X) would depend on the manufacturer and the applicable industry standards. Common standards for grooved connections include those set by organizations like the Mechanical Contractors Association of America (MCAA) or the National Fire Protection Association (NFPA).

Functions of the Grooved Butterfly Valve with Tamper Switch:
1. Flow Control: The main function of the butterfly valve is to control the flow of fluids in the pipeline. By adjusting the position of the disc, the valve can allow, throttle, or shut off the flow.

2. Grooved Installation: The grooved design simplifies installation, reducing the need for welding or flanges. This can lead to faster and more cost-effective installation.

3. Tamper Detection: The tamper switch enhances the valve’s functionality by providing a means to monitor and detect any unauthorized interference or irregularities in the valve’s operation.

When considering this valve for a specific application, it’s important to assess the compatibility with the piping system, the required flow control capabilities, and the need for tamper detection in the overall system.
