Ball Valves

EQBV

Equilibrium Ball Valves

Designed to give a high flow of water through the valve. They are supplied with appropriate size floats. In addition, when a type 'AA' or 'AB' airgap is required, the valve may be supplied with a drop arm, to enable a higher water level to be set whilst the body of the valve is located in a valve box.

Keraflo™ Aylesbury Valves

There are three options available for this delayed action self-cleaning valve, as follows:

AYLK - K Type

Designed to replace a conventional valve with adjustment on the arm to set water levels.
AYLKA - KA Type

Ideal for location in a valve box for achieving type "AA" and ”AB” air gaps. The extended arm gives a variable setting of water levels.
AYLKB - KB Type

The KB valve has a unique float system which allows high and low levels to be set, ideal for use in buildings that have an occupancy change. Can be installed in a valve box when "AA" or "AB" air gap is required or in a conventional position within a tank.

Valve Boxes

When existing tanks have been re-assessed as category 4 or 5 risk, the fitting of a valve box and shroud will enable water quality to be maintained, allowing tanks to comply with water regulations.
