Description Differential pressure bypass valve with directly readable adjustment scale. Housing made of brass. Available as straight version or angled version for space-saving installation.The bypass valve is adjusted (with closed heating circuits) in such a way that the minimum volume flow of the heat generator is maintained. The minimum volume flow is essential for heat pumps, for example, during defrosting mode and cooling mode.
