Page 2: Operation
Waterworks 700 Series Model 720 Operation The Model 720 is a pilot controlled valve equipped with an adjustable, 2-Way pressure reducing pilot. The needle valve continuously allows flow from the valve inlet into the upper control chamber . The pilot senses downstream pressure. -
Page 3: Typical Applications
The smaller by-pass valve cuts operating hours of the larger valve, achieving greater return on investment. For high differential pressure systems, see BERMAD publication 720-PD Proportional Pressure Reducing Valve. For high pressure systems, see BERMAD publication 820 Piston Actuated Pressure Reducing Valve. - Page 4 As a result, lower zone pressure reducing systems deal with greater differential pressure. The Model 720 Pressure Reducing Valves together with BERMAD’S accumulated experience address these issues and provide appropriate solutions. Higher zone pressure reducing system installation...
- Page 5 [6] Pressure Switch Lower Zone (Two-Stage) Installation When dealing with high differential pressure systems in lower zones of a high-rise building, BERMAD recommends a two-stage pressure reducing system. In addition to the typical higher zone installation, this high differential pressure system also includes: ■...
