How to choose between electric valves and pneumatic valves?
Thread Content
Everyone, please give me some advice: dizzy:. For the laboratory air duct system (DN400), I need to use one control valve and two on/off valves. Should I go with pneumatic or electric valves? Pneumatic systems also require a air supply source; moreover, due to the humid local environment and climate, separation is necessary ； The noise of the air compressor is really annoying. Electric ones are considered to be troublesome, prone to failure, and I don’t want to deal with problems in the future ； The price difference between the two is unclear. If the quantity is large, I’ll just use pneumatic power – it’s hassle-free. . . . Hey, which one is suitable after all? . . . . . . . . . .
If there is no suitable air source, it is recommended to use electric valves; after all, pneumatic valves also require electricity to generate compressed air, so it’s better to go straight for the electric option
Just one – go with the electric version; pneumatic ones require more auxiliary equipment
Since there is only one valve, it’s more convenient to use an electric valve; moreover, it is used in a ventilation system where speed requirements are not particularly strict. The air supply system required for pneumatic valves involves a higher initial investment, as well as ongoing operating costs.
Just use electric ones for the 3 units; choosing electric options is a bit more complicated, as electric actuators do come with quite a few issues
After hearing everyone’s opinions, we’ve decided to go with an electric option; it’s really troublesome to have to connect a gas supply just for these few valves. :D
Just buy a better electric valve, and that’s it. Domestic first-line products, imported ones. Good quality, excellent after-sales service, no worries
