700 Series Pressure Management Valve Flow Compensated Pressure Reducing Valve Model 7PM Patent Pending ■ Flow and leakage reduction ■ Fully self operated ■ Burst prevention ■ Extends system service life ■ Environmentally efficient ■ Water and energy saving The model 7PM Flow Compensated Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that automatically and continuously optimizes downstream pressure, correlating valve setting with demand. Features and Benefits ■ Self contained hydro-mechanical □ Does not rely on electrical power supply □ Does not require additional pipeline accessories ■ Universal fitting □ Applicable to all sizes □ Easily retro-fitted □ Low maintenance and installation costs ■ Simple design □ Does not require specialist commissioning □ Fits all “sites” ■ Double chamber design □ Moderated valve reaction □ Protected diaphragm ■ V-Port throttling plug □ Very stable at low flow □ Increased valve travel ■ Obstacle free, full bore - Free flow pass ■ In-line serviceable - Easy maintenance Major Additional Features ■ Downstream over pressure guard - 7PM-48 ■ Check valve - 7PM-20 ■ Hydraulic override - 7PM-09 ■ Pressure sustaining - 723-PM ■ Flow control -

BERMAD Waterworks Model 7PM Operation The model 7PM Flow Compensated Pressure Reducing Valve is a pilot controlled valve equipped with an adjustable, 2-way pressure reducing pilot linked to an automatically adapting flow compensating pressure adjusting system. The restriction [1] continuously allows flow from the valve inlet into the upper control chamber [2]. The pilot [3] senses downstream pressure. Should this pressure rise above pilot setting, the pilot throttles, enabling pressure in the upper control chamber to accumulate, causing the main valve to throttle closed, decreasing downstream...

BERMAD Waterworks 700 Series Pressure Management A well-planned pressure management program can significantly reduce not only volumes of real loss, but also maintenance costs by reducing occurrence of bursts and thereby extending the life of the system. Standard PRV Fixed Outlet PRVs are set to maintain a constant low downstream pressure, ensuring sufficient pressure at the systems critical point during peak demand (when line friction head loss is highest). The shaded area represents the hours and levels when pressure is higher than required. The Flow Compensated Pressure Reducing Valve, Bermad...
