Typical Applications
Pressure Reducing System for Municipal Networks
Network design requires establishing various pressure zones due to topography, distances, demands, energy costs,
reservoir availability, etc.
The pump supplies water to the network and to the reservoir. System pressure is too high for the residential
neighborhood, requiring a pressure reducing system.
In addition to the
Model 720 Pressure Reducing Valve, BERMAD recommends that the system also include:
■
Strainer Model 70F prevents debris from damaging valve operation
■
Relief Valve Model 73Q provides:
❏
Protection against momentary pressure peaks
❏
Visual indication of need for maintenance
■
By-Pass Pressure Reducing Valve saves on maintenance costs. The larger (more costly to maintain) valve operates
during peak demand. 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.
