Proportional Technology Precise 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 Technology Static & Dynamic Applications: Dynamic- Pressure/ Flow is constantly changing during the Application Example: Counter Balancer

Proportional Technology Servtronic Digital Pressure or Flow External Feedback (Closed System) Used in Static & Dynamic Applications 3/8” (G) port Only psi range, 60 SCFM Hysteresis < 0.5% Spool Sleeve Assembly Design Pressure is released when Power is lost Used With Data Acquisition Software Can be used in Very High Pulse Frequencies at Extremely Short Response Times List $

Proportional Technology Flowtronic D Flow Only External Feedback (Closed System) Used in Static & Dynamic Applications ¼”, 3/8”, ½” npt (G) ports psi range, SCFM Hysteresis < 3% Direct Acting Poppet Valve Design Pressure is released when Power is lost Used With Data Acquisition Software Precise Flow Adjustment & very responsive to outside disturbances List $

Proportional Technology Control D Stand Alone Control D is used for Open-Loop, Closed Loop, or Dual Loop Process Control It controls the Proportional Valves by Regulating the Current Auto-Tune Function automatically determines the solenoid’s maximum value More complex applications can be controlled using its additional Analog Input ports Numatics DigiCom software is included to adapt the Controller to the Control Loop Set points and Display Feedback can be set up manually Additional LEDs show Operating State and Error Messages List $

Proportional Technology Data Acquisition Software (DaS) DaS can optimally adjust the valve’s control parameters to a specific application Diagnostics Menu for Error Detection & Testing Custom Adjustments to an Application Real Time Display of: – Command Signal – Outlet Pressure – Internal Control Parameters of PID, Pressure Switch, and others Parameter Setting: -Command Signal -Zero Offset -Span -Limitation of Output Current -Ramp Function Software Included with all Proportional Valves except E Series
