{:3_63:} I just find it really strange. Why aren’t there flanges on both sides of the electric valve? It seems like a hole was made in the pipe and then an actuator was connected to it.
It feels strange; it’s as if there’s an electric mechanism connected to the pipe, without any valves attached.
It’s covered with an insulating layer on the outside, so the flanges can’t be seen
Welded electric control valve (possibly 5-position)
Then consider it welded. But even if it’s welded, there should be a slight bulge at the valve’s location; this isn’t visible at all.
