Abstract

This valve is mounted on a water pump and the valve is used together with filters which use sand or diatomaceous earth as filter medium. The valve has a leakage path so that a proportion of unfiltered water is mixed with filtered water. On regeneration filtered water is allowed to leak. The valve is used for automatic back flushing of filters. The valve is actuated by the water pressure which acts on a diaphragm at the end of the spring loaded shaft of the sliding valve.
