Installation steps of sanitary butterfly valve

The installation steps for sanitary butterfly valves are as follows:

1. Preparation before installation

Inspection and Cleaning: Check butterfly valves and pipelines to ensure no damage or contamination. Use appropriate cleaning agents to clean the inner and outer surfaces of the valve and pipeline interfaces, ensuring no residue.

Confirm compatibility: Confirm the compatibility between the butterfly valve material and the processed medium, as well as whether it meets relevant hygiene standards.

2. Installation steps

Alignment installation:

Place the butterfly valve between the pre installed two flanges, ensuring that the centerline of the valve aligns with the centerline of the pipeline.

3. Tightening bolts:

Gently insert the bolts and nuts into the flange holes and tighten them slightly to correct the flatness of the flange surface.

Use the cross tightening method to evenly tighten the flange connection bolts to avoid leakage caused by uneven stress.

4. Check the seal:

After installation, conduct a water pressure test or air tightness test to ensure no leakage.

Ensure that the valve plate can open and close freely and is not stuck by pipelines or flanges

precautions

Valve direction: Ensure that the arrow of the valve points in the direction of the flowing medium.

Avoid overtightening: When tightening bolts, apply even force to prevent deformation of the valve ring caused by overtightening.

Regular maintenance: Regularly check the sealing performance of the butterfly valve, clean the dirt inside the valve, and lubricate the moving parts.

By following the above steps, the correct installation and long-term stable operation of the sanitary butterfly valve can be ensured.
