Neptune 2 Point Controller

Pressure control in water distribution systems is a proven technique for reducing Leakage and the frequency of bursts. Normally, a PRV (Pressure Reducing Valve) is set to a fixed outlet pressure to ensure a guaranteed minimum pressure to the critical point in the network during maximum flow conditions. Pressure management using PRV controllers enables pressure to be optimized with changing demand.

 NEPTUNE II PF is an electronic controller that enables the pressure into a zone to be switched between two pre-set values (“low”and “high”) according to the demand (flow rate) or the time of day with or without a pressure override facility. This can achieve immediate water savings and enables the PRV to be controlled reliably and safely.
