Aquaflow Access valves are available with a variety of regulators with different maximum flow rates to suit the needs of specific outlets — reducing the amount of hot water going to waste to cut fuel use and metered water costs. These regulators can also react to changes of pressure in a system so the same flow rate is maintained, reg­ardless of other water use in the system or its proximity to the source of supply. These valves also include a ballstop valve for servicing of outlets. A side service port provides access to the regulator without breaking the pipework or draining the system.
