Water Purifier 3-Way Ball Valve

The water purifier 3-way ball valve is a core component for connecting water purifier pipelines. Essentially, it is a control valve featuring a 3-way structure capable of splitting a single flow into two or merging two flows into one, while simultaneously controlling the on/off status of the water flow; it is a critical element in the installation of water purification systems.

Product Description

Installation Instructions:

1. For households with a dedicated water purification outlet: Connect the T-fitting and ball valve to the threaded port on the cold water pipe located inside the cabinet.
2. For households without a dedicated water purification outlet: Connect the T-fitting and ball valve to the existing angle valve situated between your household faucet and the water supply pipe (please note: ensure you connect it to the *cold water* angle valve). Important Note:
During installation, please wrap a sufficient amount of PTFE tape around the threads to prevent water leakage.

Important Notes for Buyers:

1. For a given nominal size, the actual thread dimensions differ from the actual pipe diameter dimensions. For example, a "2-point" (1/4-inch) thread measures 12–12.5 mm, whereas the corresponding pipe diameter measures 6.0–6.5 mm.
2. All water purifier tubing in China adheres to "Imperial sizing" standards; this constitutes the industry-wide standard.
3. In Imperial sizing, the pipe diameter is abbreviated as O.D. (Outer Diameter), while the thread diameter is designated as NPTF.
