FAQs

Q1. How do Dudley fillings valves cope with high and low water pressure.

The current range of fully compliant Hydroflo inlet valves, come pre-fitted with a flow regulator, so no need for a flow restrictor. Our previous range were supplied with a flow restrictor, which needed to be removed for water pressures below 1.5 bar. As these inlet valves operate on an equilibrium principle, which uses the supply water pressure against itself to operate the valve they are suitable for use on water pressures between 0.1 bar and 14 bar.
