Signal valves for industrial use
Thread Content
Most signal valves available on the market today are signal butterfly valves used in firefighting; I wonder if there are any signal stop valves used in industrial applications? ? ? ?
I’m completely confused by the signal valve you mentioned; please don’t define it randomly – you can just describe its function
Normal pneumatic/electric on-off valves all come with position feedback; of course, it’s easy to add a position switch to a manual valve as well, though it’s not clear whether this is necessary.
A distance of just one row apart can feel like a mountain range; signal butterfly valves are commonly used in fire protection pipelines, primarily to prevent people from not knowing the open or closed status of the valve. In other words, they are manual valves equipped with a position indicator. In industrial applications, much higher control requirements are placed on valves; most isolation valves are electric/pneumatic valves equipped with position switches. In other words, due to different requirements, fire protection systems only need hand valves with feedback features, while such a simple configuration is not sufficient for industrial applications. As a result, industrial applications place higher demands on valves compared to signal butterfly valves, which is why these latter are not widely used in industrial settings.
