Delta differential pressure control valves (DPCV).
The Ballorex Delta is a differential pressure control valve which is installed in the return line. The supply line is received above the membrane through a capillary tube. When pressure increases, the rising pressure above the internal membrane forces the spindle downwards, closing the valve gradually, whereby a constant pressure drop is obtained across the system.
The range includes:
