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.
