Model 770-U

Flow Control Valve

The Model 770-U Flow Control Valve is a hydraulically operated, diaphragm actuated control valve that maintains pre-set maximum flow, regardless of fluctuating demand or varying system pressure.
 

Features and Benefits

  • Line pressure driven – Independent operation
  • Hydraulic flow sensor (upstream installation)
    • No moving parts
    • No electronic components
    • No need for flow straightening
  • 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

Typical Application

 

Distribution Networks

System design starts from expected flow range that determines major system components:

  • Pump stations: Characteristics, location, quantity
  • Supply lines: Layout, class, size
  • Reservoirs: Location, volume, head

Significant deviation from designed flow range might disrupt water supply or even damage system components. Appropriate design, placement, and use of the Model 770-U protects the system from excessive flow. When pressure reducing is also required, choosing the Model 772-U, instead of the Model 770-U, completes the solution.
