WW-720-PD
Proportional Pressure Reducing Valve


The Model 720-PD Proportional Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower downstream pressure at a fixed ratio.
 

Features and Benefits

Line pressure driven – Independent operation
Elegant simplicity

  • Most cost effective
  • Simple to maintain
  • Minimal external accessories

Variety of reduction ratios – Perfect mission matching
Built-in check feature – Replacing line sized check valve
In-line serviceable – Easy maintenance
Double chamber

  • Moderated valve reaction
  • Protected diaphragm

Flexible design – Easy addition of features
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

There are two major applications for the Model 720-PD Proportional Pressure Reducing Valve:

Long downhill lines:

  • Systems A1 and A2 prevent the downhill line from exceeding its pressure rating.

High differential pressure systems:

  • System B reduces cavitation damage and noise level by distributing the load of the high differential pressure.
  • System C illustrates protecting a circulation valve from high differential pressure and resultant severe cavitation.
  • System D shows protecting a level control valve from high differential pressure.
