Product Description

A circular galvanized manual valve is a type of flow control device used to regulate the flow of fluids in plumbing systems. It operates manually, meaning that an operator must turn the valve handle to open or close the valve. The primary functions of this type of valve include:

1. **Flow Control:** Adjusting the rate at which fluids pass through the system.
2. **Shutoff:** Completely stopping the flow of fluid when necessary.
3. **Pressure Regulation:** Helping to maintain consistent pressure within the system.
4. **Isolation:** Allowing for sections of the plumbing system to be isolated for maintenance or repair without shutting down the entire system.

The structure of a circular galvanized manual valve typically includes several key components:

1. **Valve Body:** The main cylindrical component made from galvanized steel, which provides strength and corrosion resistance.
2. **Handle or Lever:** A mechanical part attached to the top of the valve that allows for manual operation. This can be a simple lever, a wheel (wheel-handle), or even a gearbox for larger valves.
3. **Stem:** A rod that connects the handle to the internal mechanism of the valve. When the handle is turned, the stem moves up or down.
4. **Seal or Seat:** The part where the stem presses against to stop the flow. This is usually made from materials designed to create a tight seal when closed.
5. **Gaskets or Packing:** Materials used to ensure there are no leaks around the stem as it moves within the valve body.
6. **Connection Points:** Ends of the valve where it attaches to pipes or other sections of the plumbing system, often threaded or flanged for secure connection.
7. **Galvanized Coating:** A layer of zinc applied to the valve body to protect against rust and corrosion, extending the lifespan of the valve.

Overall, a circular galvanized manual valve is a robust and reliable component commonly found in residential, commercial, and industrial plumbing systems due to its durability and ease of use.
