Tother plumber has just come back.
£85 plus VAT.
He's got the job.
Just have to arrange a time.

Simlar yes, though the impulse generator would be more like a delay off timer in electrics, you has to zero the inlet pressure (or at least the pressure on port 12, if present) to reset it. The flowmaster is closer to a pilot operated sol valve imo. Flow over the diaphragm = open. No flow = closed. The area under the diaphragm is larger so the flow effectively forces the valve open until you close the pilot, which has a spring to give it a hand. Not much overall force in the end , which is why you need half a bar diff. to make em work.
The IP was a great step forward and simplified pneumatic logic no end.
Ironically, looked down on by purists back in the day.
Did i just do a "Stan" ?

I still clean etc, just hate it.
Lets face it, we ALL hate it.
Being able to send a short signal to another valve down an airline with no need to do anything else, no air to lose, no reset to do, no springs or owt else to worry about, to simply switch it, made it so much easier for mugs like me who had to design circuits!Simlar yes, though the impulse generator would be more like a delay off timer in electrics, you has to zero the inlet pressure (or at least the pressure on port 12, if present) to reset it.

Ideal in dodgy environments where using electrics to do the same would have been a no-no.
I vaguely remember the sub-circuit you would have to build to do the same thing in other makes like Schrader or Martonair, who were our big competitors at the time. Flipping nightmare. Hee Hee!
You put your cat in the washing machine??
Them pussy's are smelly fings they needs constant cleaning.

I have tried to find an image of what we used to sell back then, just can't.Simlar yes, though the impulse generator would be more like a delay off timer in electrics, you has to zero the inlet pressure (or at least the pressure on port 12, if present) to reset it.

It looked basically like a fat little brass cylinder.
The little piston inside it had a wider surface area at one end than the other and there was a thin drilling that went all the way through it.
When it was operated or actioned , momentarily, (i.e. zeroing it soon after) air went into the smaller chamber and out the other side to whatever was going to get the impulse. Meanwhile air passed down the drilling into the slightly bigger chamber where the bigger surface meant that that end pushed the cylinder back to where it started, cutting off the signal air and resetting itself until it was operated again.
This happened in nearly no time at all. Beautiful in its simplicity. I think I have oversimplified this a bit but it is broadly how it worked.
I have no idea what "port 12 " is! I suppose this must be on a much more modern version of it. I haven't touched pneumatics since 1976!
So this is for anyone who has no idea of what I am on about. sorry I can't put a pic up.
And yes you did just do a STAN! Don't let the fame get to you!!!

Nah, that's your new mobile kitchen units. Sink on the left, hob on the right! Tall fridge on the far left, tall freezer on the far right.
Very "industrial" vibe and a long way away from your copper pans!

Yer not surpost to wash yer cat in the washing machine.

One would hope they din't have a shunt to avoid loss, even a little bit. Measuring like a clamp meter does instead. Precision should be quite good. Does yer have yer own meter to measure the currunts and volts? Modern leccy meters charge a bit more if yer gorra lot of inductive loads.
What does that mean, please?
