Model 736

The Model 736 Differential Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that sustains minimum pre-set, differential pressure between two points regardless of fluctuating flow or varying upstream pressure.

Product Features & Benefits
  • Line pressure driven – Independent operation
  • 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 Product Applications

In filtration systems there are two cases when by-passing the filter is essential:

  • Blocked filter (potentially causing element collapse)
  • Demand for emergency fire water

The Model 736, installed as a by-pass, progressively compensates for excessive demand. Adding feature “S” incorporates alarm signaling attribute.
