PRODUCT INFORMATION

Bermad WW772-U – Flow Control and Pressure Reducing Valve

The Model 772-U Flow Control and Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve with two independent functions. It maintains both pre-set maximum flow and it reduces higher upstream pressure to lower constant downstream pressure, regardless of varying demand or upstream pressure.

Controlling over demand & pressure

• Balancing flow via parallel pressure reducing valves
• Controlling pipeline fill rate
• Pump cavitation & system over pressure protection
• Compensating during groundwater drawdown

FEATURES & 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
