The Model 723 Pressure Reducing and Sustaining Valve is a hydraulically operated, diaphragm actuated control valve with two independent functions. It sustains minimum pre-set upstream pressure regardless of fluctuating flow or varying downstream pressure, and it prevents downstream pressure from rising above maximum pre-set regardless of fluctuating flow or excessive upstream pressure.
Features and Benefits
Line pressure driven – Independent operation
In-line serviceable – Easy maintenance
Double chamber design
- Moderated valve reaction
- Protected diaphragm
Flexible design – Easy addition of features
Variety of accessories – Perfect mission matching
"Y" or angle, wide body – Minimized pressure loss
Semi-straight flow – Non-turbulent flow
Stainless Steel raised seat – Cavitation damage resistant
Obstacle free, full bore – Uncompromising reliability
V-Port Throttling Plug – Low flow stability
Water is pumped from a deep well to the reservoir through a line also supplying nearby consumers along the way. Water is then supplied from the reservoir to both higher and lower elevation consumers. Both parts of the system require pressure sustaining and reducing solutions.
