The rubber lining, typically made of natural or synthetic rubber compounds, is bonded to the internal surfaces of the valve body and gate. This lining acts as a barrier, protecting the metal components from corrosive fluids and ensuring tight sealing.

The gate, which controls the flow of fluid, moves perpendicular to the direction of flow. When the gate is fully raised, it allows unrestricted flow through the valve. Conversely, when the gate is lowered, it blocks the flow, effectively isolating the downstream section of the pipeline. The gate is connected to the stem, which extends outside the valve body, allowing for manual or automated operation.

2. Benefits of Rubber Lined Gate Valves:

a. Corrosion Resistance: The rubber lining provides excellent corrosion resistance, making these valves suitable for handling corrosive fluids like acids, alkalis, and salts.

Ceramic semi ball valves are also known for their long service life and low maintenance requirements.

Installation

1. Choose the right valve for your application. Consider the pressure, temperature, and flow rate requirements of your system. You should also select a valve that is compatible with the fluid being used.

2. Prepare the piping. Cut the pipe to the desired length and deburr the edges. If the valve is being installed in a horizontal line, make sure that the valve is installed with the stem in the vertical position.

3. Install the valve. Apply a sealant to the threads of the valve body and then screw the valve into the piping. Tighten the valve until it is snug.

4. Connect the valve to the actuator. If the valve is being actuated by an electric actuator, connect the actuator to the valve stem. If the valve is being actuated by a pneumatic actuator, connect the actuator to the valve body.

5. Test the valve. Open and close the valve several times to make sure that it is functioning properly.

Maintenance

1. Inspect the valve regularly. Look for signs of wear or damage to the valve body, stem, or ball.

2. Lubricate the valve stem. The valve stem should be lubricated with a light oil or grease every six months or as needed.

3. Replace the packing. The packing around the valve stem should be replaced every two or three years or as needed.

4. Rebuild the valve. If the valve is leaking or if the stem is damaged, the valve should be rebuilt. A valve rebuild kit can be purchased from the manufacturer.

Troubleshooting

If you are having problems with a ceramic semi ball valve, the following troubleshooting tips may be helpful:

1. The valve is leaking. Tighten the packing gland or replace the packing. If the valve is still leaking, the valve may need to be rebuilt.
