Key Points for Installation and Maintenance of Bellows Stop Valve WJ25F-1.6P

The bellows stop valve WJ25F-1.6P, as a valve used in the hydrogen cooling system pipeline of generators, is crucial for its correct installation and effective maintenance of performance and system safety. The following are some key points to pay attention to when installing and maintaining globe valves.

1. Installation position: It should be ensured that the installation position of the shut-off valve is reasonable, considering the pipeline layout, and ensuring that the bellows can freely expand and contract.
2. Valve direction: The valve will be marked with a flow arrow, which needs to be installed in the direction indicated by the arrow.
3. Tightening bolts: During the installation process, ensure that the fastening bolts are evenly stressed and not too tight or loose. Avoid excessive tightening that can cause damage to the bellows.
4. Pipeline preparation: Before installation, ensure that there are no debris, cutting objects, or other substances that may cause damage to the valve inside the pipeline.
5. Valve support: On long pipelines, it is necessary to provide appropriate support for bellows valves to reduce valve load.
6. Regular inspection: Conduct regular inspections, including the appearance of the bellows, whether there are leaks in the connecting parts, and whether the valve operation is flexible. Pay special attention to the valve and flange connections and check for leaks.
7. Valve stem lubrication: Regularly lubricate the valve stem to ensure smooth movement and prevent rusting.

Through correct installation and effective maintenance, the bellows stop valve WJ25F-1.6P can be ensured to operate stably and reliably for a long time.
