What type of threads do threaded valves have?

Threaded valves are designed with internal threads that allow them to connect securely with pipes or fittings that have external threads. This internal threading enables a tight seal when the valve is screwed onto the corresponding pipe or fitting, preventing leaks and ensuring proper flow control within plumbing systems. Internal threads provide a robust mechanical bond between components, critical for maintaining system integrity under pressure.

In contrast, external threads are typically found on pipes or it may also be utilized in fittings that connect to valves. Composite and layered threads are not standard terms used in plumbing for describing the threads on valves; hence, they do not apply in this context. Understanding the design and application of threaded valves is essential for achieving effective plumbing installation and maintenance.
