Which is why I operate gently by hand. You only need about 10 PSI.
Me too. The pair I tried were bespoke chrome rad isolation valves from Screwfix; looked nice and neat and would have been terrific had they done what it said on the tin. However mine leaked right from the off, so I had to dump them, which necessitated taking the rad off
*again* and tweaking the pipework to fit, so I wasn't best pleased. Never tried them again...David
It would have to be in the tail - between the rad and the valve - to act in the way you describe. I've seen tails with drain points in them, but I can't recall seeing any with service valves. Of course, someone may know differently!
The downside of this arrangement is that a large rad full of water would be bl**dy heavy to lift off and carry outside.
Yes I do! (see other post). These were definitely a Screwfix thing, but AFAICS they've discontinued them (unsurprisingly...)

Right! If the balls were as reliable as those in their cheapo service valves, it may explain why they've stopped doing them. [I've had several service valves fail. They don't leak, but they just don't turn off - which rather defeats the object of them! The screw turns, but the ball apparently doesn't.]
