The Danfoss ARV22 Auto By‑Pass Valve (part 099‑106300) is a compact, angled‑pattern control valve for 22 mm pipework that automatically opens and closes to maintain minimum flow in heating systems. It’s designed to reduce noise and protect low‑water content boilers by balancing flow and pressure as radiator thermostats adjust.
