Being as how its my first post :cb

In the how to do section you say make sure the arrow is facing the right way because it will not work ::b

For your records that is not why the arrow is there. shock emoticon.

The arrow is there to signify which end can be safely dismantled if the pipe is under pressure.

The little ball in the middle is held in with an spring clip, if you undo that end the ball will fly out :cb

Your first post and already you are trying to be a smart arse :roll:

Sorry boss it was meant as an light hearted first post :boxing:

However since you pointed out my mistake. From an operational point of view it will make no difference which way the valve is fitted, The arrow is not an directional arrow.

May I suggest you stick one on an hose pipe an see what happen :-)

Ha Ha,

No thanks I will take your word for it :lol:

The arrow is not much use then if someone has fitted it the wrong way around :lol:

I'm sure someone said that they had reduced flow from one that was fitted with the arrow pointing in the wrong direction :scratch:

No, as I said it is to show which end can be dismantled.

If you undo the other end the ball will fly out, and that will cause a big panic to most DIYers. Have a look in the ends and you will see what I mean.

I will say if they are used as local isolating valve its not usually a problem, the problem only becomes a problem when they are used inline, say to valve of while you are doing some work on the pipes

So either way, if you 'think' it's the direction it should be fitted (with flow) or the direction from which the ball won't fly out, you should always fit it with the arrow pointing in the direction of the flow?

That's a really useful post eloquently put. :roll:

No Jaeger, if they're inline you may want to work up or down stream, the arrow shows you which end you can safely disconnect.

b*llocks.

Why would I ever want to open the down stream side of an isolating valve in line on a live pipe?

But wait, how would I know if it was down stream?

Why the arrow on the isolating valve would be pointing the other way!

Why do they put the arrow on there then, the better quality Ballofix valves never do.

If you have a problem with my post try asking the manufacturer. :roll:

Why?

The manufacturer won't help you here, I have a shovel spare if you want to borrow it.

I fix them with the flow, so I won't have a problem.

But you've not answered my question

... and now I've got another.....

How would the average DIY'er know he's got a "better quality Ballofix valve" rather than a cheap import that doesn't have an arrow because the cheap easterners didn't have one put in the cast?

... and another....

How much time have you spent on here reading posts and finding out who's who's? 3 nanoseconds? 4 maybe?

so you drain the heating out, cut the flow and return pipes and stick a couple of isolating valve on the pipe so the client can have the heating back on.

Which way are the arrows now.

scruff,
You're missing it completely WOOOOOOOOOSH that was it passing over your head.

What heating? You've just cut it out?

If you mean, to let the client have some hot water?

You're trying to trick me know adding flow and return, well both arrows would point the same way which would be pointing to where there is no pipe.

HINTON IS THE GOD!

No old boys club, no invite required. Humility civility and general easing yourself in is sometimes a good idea, in fact you’re the proof of the pudding but hey you knock yourself out.

Pretend, you want to alter some pipework to put a door in.

Yes could be an secondary circuit.

A change of mind then, but why ? you always fit them with the flow, or is there a good reason not too.[/quote]
