Proportional Technology Precise Control of Pressure and Flow

Proportional TechnologyPrecise Control of Pressure and Flow

Proportional Technology• What are Proportional Valves?• Electronically Controlling the Pressure, Flow, or Both• How do we Control it?• Thru Internal or External Feedback• Internal- Built in Pressure Transducer in the Valve• External- Pressure Transducer, Load Cell, or Linear Transducer• PID Controller makes adjustment based on feedback & set point • PID= Proportional- Integral- Derivative

Proportional Technology

Static & Dynamic Applications:Static- Pressure/ Flow is Set for an Application and remains until Job is Done

Example: Glue Dispensing

Proportional TechnologyStatic & Dynamic Applications:Dynamic- Pressure/ Flow is constantly changing during the Application

Example: Counter Balancer
