ORIFICE APPLICATIONS
• Pressure reduction (e.g. to reduce relief valve
requirement)
• Providing desired flow at a given pressure drop
• Minimum recirculation flow on a pump
• Strainer backwash flow control
• Shaping pump curve
• Pumps in parallel (make both pumps work)
• Changing Cv of a valve (parallel and series
orifices)
• Balancing flows with varying pressure
• Balancing flows
• Critical flow measurement (gas)
• Constant Flow Purge system for a continuously
decreasing supply pressure
• Helium blending patent
