ABSTRACT:
A dilution valve dilutes a liquid feed concentrate with water, to give a dilute feed for feeding to piglets. The valve has a plunger (20) which reciprocates within a mixing chamber (66), to which the water and liquid feed concentrate are admitted through separate valves (48,70). Water pressure drives the plunger (20) in a charging stroke, during which water and liquid feed concentrate are admitted to the mixing chamber (66). A change-over spring (60) causes the plunger (20) to change from a charging stroke to a delivery stroke, during which dilute feed is delivered, the plunger (20) undergoing alternate charging and delivery strokes driven by the pressure of the incoming water.
