What are the main causes of waterproof and breathable valve failure

1. Waterproof and breathable valve body: The corrosion and wear of the inner wall of the valve body should be checked frequently, especially for valves used in harsh process conditions such as corrosive media, high pressure differences, and cavitation. Their pressure resistance strength and resistance must be guaranteed. Corrosion and wear resistance.

2. Waterproof and breathable valve core: Because the waterproof and breathable valve core plays the role of regulating and cutting off the fluid, and is a movable intercepting element, it is most seriously affected by the erosion, corrosion, and particle collision of the medium. In the waterproof and breathable membrane manufacturer, the high pressure difference , it is more susceptible to damage under the condition of cavitation, so check whether its parts are damaged, worn, corroded, and whether they need to be repaired or replaced.
3. Waterproof and breathable valve seat: The joint surface of the valve seat is the key to ensuring that the valve is closed. It is also subject to serious corrosion and wear. Moreover, since the waterproof and breathable valve will have media penetration, the inner surface of the thread that fixes the valve seat is often corroded and loosened. This part should be specially inspected.

4. Waterproof and breathable valve stem: Check whether the connection between the waterproof and breathable valve stem, the valve core and the push rod is loose, and whether there is excessive deformation, cracks and corrosion.

5. Gaskets and O-rings: These vulnerable parts must not be cracked or aged.

6. Waterproof and breathable valve packing: Check whether the polytetrafluoroethylene or other packing is aging, lack of oil, or deteriorated, and whether the packing is tight.
