Tapping Valve

Definition

A tapping valve is a device used to open or close a duct, pipe, or other passage, or to regulate flow. It is inserted into an existing pipeline by piercing the wall of the pipe and thus tapping into the flow.

Purpose

Tapping valves are used to connect new branches to existing pipelines without interrupting the flow. This is essential for maintenance, repairs, and expanding pipeline networks without significant downtime.

Examples of Use

1. Water Supply Systems: Tapping valves are used to add new service connections to municipal water mains without shutting off the entire system.
2. Gas Lines: In gas distribution networks, tapping valves allow for safe and efficient addition of new connections or branches.

Related Terms

• Gate Valve: A valve that opens by lifting a barrier (gate) out of the path of the fluid.
• Ball Valve: A valve that controls the flow of liquid or gas by means of a rotary ball with a bore.
• Butterfly Valve: A valve that regulates flow with a rotating disk.

Notes

• Installation: Proper installation is critical to ensure a secure and leak-free connection when tapping into existing pipelines.
• Pressure Considerations: Tapping valves must be designed to handle the pressure of the pipeline into which they are installed.
