WW-730-55
Pressure Relief/Sustaining Valve


The Model 730-55 Pressure Relief/Sustaining Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve that sustains minimum pre-set, upstream (back)pressure regardless of fluctuating flow or varying downstream pressure. It also either opens or closes in response to an electric signal. When installed as a circulation valve, the Model 730-55 relieves excessive line pressure when above maximum pre-set.
 

Features and Benefits

Line pressure driven – Independent operation
Solenoid controlled

  • Low power consumption
  • Wide ranges of pressures and voltages
  • Normally Open, Normally Closed, or Last Position

Balanced seal disk – High relief flow capacity
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 Applications

Circulating Valve with Reservoir Overflow Protection

  • Water is supplied to the consumer network from the reservoir or directly from the major supply network:
  • During pumping from the reservoir, the Normaly Closed Model 730-55, with energized solenoid, serves as a circulation valve.
  • During direct supply, pressure might be higher than pilot setting, possibly causing reservoir overflow. The de-energized solenoid keeps the Model 730-55 closed, preventing reservoir filling from this source.
