These switches or valves are commonly found in residential, commercial, and industrial settings. Examples of clean water valve switches include:

1. Ball Valve: A ball valve is a type of valve that uses a spherical ball with a hole in it to control the flow of water. When the valve is open, the ball is aligned with the pipe, allowing water to flow. When the valve is closed, the ball is turned perpendicular to the pipe, blocking the flow of water.

2. Gate Valve: A gate valve is a valve that uses a gate or wedge-shaped disc to control the flow of water. When the valve is open, the gate is lifted, allowing water to pass through. When the valve is closed, the gate is lowered, creating a seal and stopping the flow of water.

3. Globe Valve: A globe valve is a type of valve that uses a disc and a seat to regulate the flow of water. The disc moves up and down to control the opening and closing of the valve, allowing for precise adjustment of the flow rate.

4. Solenoid Valve: A solenoid valve is an electromechanical valve that uses an electric current to control the flow of water. When the electrical signal is applied, the valve opens or closes, allowing or stopping the flow of water.

The specific type of clean water valve switch used depends on the requirements of the plumbing system, including factors such as water pressure, flow rate, temperature, and intended use.

It's important to note that the selection, installation, and maintenance of clean water valve switches should be done in accordance with local plumbing codes and regulations to ensure safe and efficient operation.

In summary, a clean water valve switch is a device or valve used to control the flow of clean water within a plumbing system. Various types of valves, such as ball valves, gate valves, globe valves, or solenoid valves, can be used as clean water valve switches to regulate water flow, adjust flow rates, or divert water to specific outlets or areas.
