3. OPERATING DESCRIPTION
The DeviceNet VP51 is a programmable electronic proportional control valve.
The pneumatic section is a diaphragm actuated precision glandless spool valve, pilot pressure applied to the
pneumatic section controls the output pressure of the unit.
The pilot pressure is generated and controlled electronically. The feedback signal from the outlet port is
compared to the control signal required and ensures a consistent, stable output pressure.
The electronics system requires a nominal 24V DC supply signal (supplied from DeviceNet). With a 150 psi
standard unit, the user can define their requirements through DeviceNet parameters, and set the application
parameters needed for the unit, i.e. speed, proportional & integral gain, thresholds etc.
