What is a wafer butterfly valve?
A wafer butterfly valve is a type of industrial valve used for regulating and controlling the flow of fluids in a pipeline. It consists of a flat, disc-shaped closure element (resembling a butterfly) that rotates on a spindle to control the flow of fluid.
Wafer butterfly valve installation:
- Verify the valve size: Ensure that the valve size matches the pipe size where it will be installed.
- Check the valve for any damage: Inspect the valve body, disc, stem, and seals for any signs of damage or defects. If any defects are found, the valve should be repaired or replaced before installation.
- Prepare the pipe: Clean the flange faces on both sides of the pipe and remove any debris or foreign materials. Ensure that the flange faces are smooth and free of burrs or scratches.
- Position the valve: Place the valve between the two pipe flanges, making sure that the valve's arrow is pointing in the direction of flow.
- Align the valve: Align the bolt holes on the valve flanges with the corresponding holes on the pipe flanges. Use alignment pins to hold the valve in place.
- Install the bolts: Insert the bolts into the bolt holes and hand-tighten them in a crisscross pattern. Do not fully tighten the bolts yet.
- Tighten the bolts: Using a torque wrench, tighten the bolts in a crisscross pattern according to the manufacturer's specifications. Do not overtighten the bolts, as this can damage the valve or the flanges.
- Check for leaks: Test the valve for leaks by filling the pipe with water or another suitable fluid and pressurizing it to the maximum operating pressure. Check for any leaks around the valve body or seals.
- Finalize the installation: Once the valve has been successfully tested, finalize the installation by removing the alignment pins and installing any necessary accessories, such as handles or actuators.
Middleeast valve is a topmost Wafer butterfly valve supplier in Dubai and is known for its compact design, ease of installation, and cost-effective operation. However, they are typically used for applications with moderate temperature and pressure conditions and may not be suitable for high-temperature or high-pressure applications without proper design considerations.
