Pneumatic ventilation butterfly valve
Thread Content
Pneumatic ventilation butterfly valve, double-acting cylinder, non-explosion-proof, DN350, 0.25MPa. Can it perform 500 opening and closing cycles in 8 hours?
The solenoid valve in the power air supply control circuit is capable of operating at a frequency of 500 times per 8 hours; the butterfly valve can also open and close at this frequency. However, its sealing performance is another matter~~~~~~
Ventilation butterfly valves are not designed to be airtight in the first place. . With such high-frequency switching, as long as the settings are correct, ordinary valves can also be used, though their lifespan is likely to be short. . Especially for the valve stem, which is subjected to such high-frequency operations, special attention should be paid during production. . . .
Such high-frequency operations place a significant strain on the sealing surfaces, packing, and cylinders
This isn’t a big problem; there are companies in the country that have good performance
