Dudley Delay Fill Hydroflo Float Valves are Equilibrium Quiet Filling Part 4 Valves, manufactured to BS1212 standards. These are available in side or adjustable bottom inlet from 8″ to 11.1/2″, with either a plastic or brass tail option to help prevent cross-threading. The unique float arm makes it impossible for the float to become detatched. Filter removal is made quick and simple by providing a key attached to every divertor, without causing any damage to the valve. Simple and easy to install, this valve is a great replacement for any cistern. The valve will save water by only opening once flushing is complete, this supports the Code for Sustainable Homes and BREEAM.
