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.

The Honeywell Home DU145‑3/4B 22 mm Differential Bypass Valve ensures consistent boiler flow and stable system pressure by automatically regulating differential pressure in heating circuits. With 22 mm compression connections, a wide differential pressure range (0.1‑0.6 bar) and high flow capacity, it is ideal for modern central heating systems requiring reliable bypass control.
