Everyone, can a pneumatic control valve use steam as a power source? I’m currently in communication with a company regarding an issue with a control valve; they mentioned steam. I heard about it for the first time; maybe I’m just uninformed. Those of you who work with instruments, please help to verify this.
No, there are many factors to consider when using steam: temperature, condensate water, and so on
Is it some kind of special pneumatic head? It’s similar to a steam turbine, but using steam for propulsion is too troublesome and results in high energy consumption; its use is not recommended
I’ve never seen such a special situation; in any case, the concern is freezing and the impact of high temperatures on the components.
It doesn’t seem reliable! Why use steam? Is there no compressed air?
It’s either a mistake in wording or a mishearing:victory:
The instrument air pipeline for my pneumatic valve has strict requirements regarding the internal air dew point, and dehydration is necessary. I’ve never heard of steam-powered ones; moreover, in pneumatic valve systems, the flow isn’t continuous – once it stops, doesn’t the fluid cool down and liquefy? How is pressure maintained? And how are corrosion issues addressed?
I’ve heard it for the first time – it must be much more complicated than ordinary pneumatic systems, requiring hydrophobic treatment, pressure relief, and things like that.
Compressed air is so cheap; why use steam? You must have heard that wrong
