What to Note When Using Insulating Ball Valves

    Thermal insulation ball valves and flanged gate valves belong to the same type of valves. The difference lies in their closure, which is a sphere that rotates around the valve body's centerline to achieve opening and closing. Ball valves are primarily used in pipelines for cutting off and...

Divert and alter the flow direction of the medium. The two-piece ball valve and the three-piece ball valve are a new type of valve widely adopted in recent years, typically installed horizontally.

Thermal insulation ball valves have a wide range of applications, mainly including systems in the oil, chemical, metallurgy, and food industries.

Specific application scenarios include:

1. Petroleum and Chemical Industry: Insulated ball valves are used in the petroleum and chemical sectors for conveying high-viscosity media that solidify at room temperature, such as heavy oil and adhesives.

2. Metallurgy: In the metallurgy industry, insulation ball valves effectively handle high or low-temperature media, ensuring the stability of the production process.

3. Food Industry: Insulating ball valves ensure temperature control of the medium, suitable for processes requiring strict temperature control.

In addition, the insulation ball valve boasts excellent thermal insulation properties, effectively reducing heat loss in the medium within pipelines, making it suitable for various industrial applications requiring temperature control.

Important considerations for using insulation ball valves include the following aspects:

   Cleaning and InspectionBefore installation, remove the protective caps on both sides of the flange and flush the valve clean with it fully open. Simultaneously, conduct a complete machine test according to the specified signals (electric or gas).

Ensure no vibration affects performance during transportation.

Installation Requirements: During installation, do not use the actuator part of the valve as a lifting point to avoid damaging the actuator and accessories. The insulation ball valve should be installed in the horizontal or vertical direction of the pipeline.

The pipelines in the vicinity should not exhibit sagging or be subjected to external forces; pipeline supports or bracing can be used to eliminate deviations in the pipeline.

3. Connection and Fastening: After the pipeline is connected, the flange bolts must be cross-tightened with the specified torque to ensure a secure connection.

Non-metallic parts should be removed immediately after cleaning and should not be soaked for extended periods. When assembling, the bolts on the flange should be tightened symmetrically, gradually, and evenly.

To prevent damage to the sealed surfaces of parts, especially non-metallic components.

5. Lubrication and Sealing: During assembly, it is necessary to use a lubricant compatible with the ball valve material, applying it to the sealing groove, rubber seals, the sealing surface of the valve stem, and the friction surfaces to ensure proper lubrication and sealing.‌

6. Operation Standards: During use, ensure that the filling sleeve/cover is not tilted during installation, and the clearance around the valve stem and filling cover hole should be even. Apply lubricating oil before installing the filling material, and tighten until there is no leakage.

By following these precautions, the lifespan of the insulation ball valve can be effectively extended, ensuring its proper operation.
