Technical design
The pre-adjusted gland can also be replaced when the system is under pressure
Using the AV225 mounting tool, the whole valve insert can be checked and / or re-
placed without draining the system
Determination of the length of nickel-plated connecting pipe of 15 mm dia.: effective
pipe length = distance of radiator threads minus 44 mm
Mechanical design
These valves allow the flow rate to be pre-adjusted by limiting the stroke (kv-value). A
pre-adjusting screw with the reference numbers 1 to 7 is located under the protective
cover.
The special design and material of the valve plug allow perfect flow control and tight
shutoff.
