Brief discussion on the advantages and daily maintenance methods of high-platform ball valves

The advantages of high platform ball valves 1. Easy installation: The high-platform ball valve adopts a new ISO5211 platform structure, has a platform on the stem, and can be installed directly with the actuator without a bracket, making it easy to install and disassemble. When installing the actuator, the ordinary ball valve needs to be equipped with a bracket first, and the valve fastening bolts should be lengthened, which is not only troublesome but also expensive. 2. Appearance and process: The high-platform ball valve adopts the silicon sol casting process, and the product appearance is better than the ball valve manufactured by ordinary process.

Why should the gate valve shut-off valve be equipped with a sealing device?

Gate valves and globe valves require an upper sealing device, which is mainly based on the following considerations: I. Prevention of media leakage and filler protection Prevent media leakage: When the gate valve and globe valve are closed, the stem is in a stationary position. Without an upper sealing device, the medium may penetrate upward along the gap between the stem and the valve body, causing the media to leak. The upper sealing device can effectively prevent the leakage of the medium and ensure the performance and safety of the valve. Filling protection: The packing letter is usually sealed with flexible materials such as asbestos and polytetrafluoroethylene for long-term contact media.
