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.
Features and 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
Where suction pressure regimes vary, the Model 736 is needed to limit pump flow by sustaining pump differential pressure, preventing pump overload and cavitation damage caused by excessive demand.
Adding check feature “20”, saves the cost of a line sized check valve.
