Rated 1 out of 5 by from Adjustment feature ineffective I had purchased an ABV valve that i later found out was not suitable. The confined space i had to fit it meant i needed a straight valve, so i purchased this straight valve. A simple test to check the valve is to blow through it, in the correct direction and start adjusting the valve, it should become more difficult or easier to blow through depending on which way you are adjusting it. With this new straight type when you repeat this test the resistance is the same open or closed it makes no difference. ,

Rated 5 out of 5 by from It did the job. I replaced it for the manual valve which was fitted by previous owner. It dramatically increases the water flow which effectively heats the radiators significantly faster. I can feel the difference. Yet it maintains the water flow to the boiler when all the timed TRVs are shut. I can hear the flow through it when it opens. I kept it at factory default 0.2 Bar. The boiler's Inflow and outflow water temperature difference is now 10-20' C depending on the duration boiler has been running and the rooms' temperatures.
