I've ripped out thousands of meters of plastic pipework blocked solid loads of which is barrier. Yes copper blocks but but far far less if you imagine the amount of copper systems fitted in comparison to plastic and the length of time the copper was put in before plastic was even invented copper...
Plastic pipework barrier or not is prone to blockages in heating systems. Any flexible pipework is far more likely to become restricted by dirty systems than copper pipework is. I would urge you to replace the system with copper pipework. It is more work and harder work for,installer and...
Better yes because the motorised valve needs wiring to work if you’re going to use it simply to shut of you might as well use a gate valve. But as it’s going to need draining to fit it just stick the anti gravity valve it like it’s supposed to have. Get yourself a suitably experienced heating...
If it’s gravity HW pumped heating and upstairs rads are heating then it’s either never had an anti gravity valve fitted or the anti gravity valve is passing.
That’s not a pre magnet one the pre magnet one was a dirt separator which caught more than any of their magnet versions do that looks like their first magnet effort (MB1) the magnet is internal and not removable.
