The Quill Auto-filling Valve is a spare part for the Quill Nipple Drinker. It does not have an automatic cut off which makes it easier to set up from empty & regulates the drinkers water level if it ever gets too low.

Our Quill Valves are made using plastic parts made in England from virgin high grade plastic and are all hand assembled at our factory in Dorset to ensure quality control. All components are available individually and can easily be replaced, please click here.
