2. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   The welding of metals differs from soldering and brazing in that the joint is made without adding a lower-melting-point material (e.g. solder); instead, the pipe or tubing material is partially melted, and the fitting and piping are directly fused. This generally requires piping and fitting to be the same (or compatible) material.

4. Flow control valve - Wikipedia

   en.wikipedia.org/wiki/Flow_control_valve

   Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as automatic ...

5. Ball valve - Wikipedia

   en.wikipedia.org/wiki/Ball_valve

   A ball valve is a flow control device which uses a hollow, perforated, and pivoting ball to control fluid flowing through it. It is open when the hole through the middle of the ball is in line with the flow inlet, and closed when it is pivoted 90 degrees by the valve handle, blocking the flow. [1]

6. Copper tubing - Wikipedia

   en.wikipedia.org/wiki/Copper_tubing

   Solder fittings are smooth and easily slip onto the end of a tubing section. The joint is then heated using a torch, and the solder is melted into the connection. When the solder cools, it forms a very strong bond that can last for decades. Solder-connected rigid copper is the most popular choice for water supply lines in modern buildings.
