Constant Pressure

May 1, 2002
Flomatic Valves, a member of Danfoss' Water Valve Division, introduces the CycleGard II, which features an unleaded pilot. The CycleGard II incorporates an adjustable unleaded pressure-reducing pilot that can give a constant pressure from 30 psi to 300 psi. The unit is designed to give a constant regulated downstream pressure and eliminates pump cycling during normal operation. It turns any pump into a variable flow pump, and features easy field-adjustable controls for irrigation, booster pumps and water well systems. Flomatic Valves
