2-Way Servo Proportional Valves
Series TFP
Operation Manual
1. Introduction
Parker 2-way servo proportional valves with VCD
®
technology have an integrated electronics and re-
quire only one sole electrical common for the control
system. Different flow sizes are available to achieve
an optimal adaption for different applications.
Characteristics of Valve Driver
The described integral electronic driver combines all
necessary functions for the optimal operation of the
valves. Thanks to its excellent dynamic the valves
are usable within closed loop control applications.
The most important features are:
• high dynamic actuator principle with special
designed electronic driver
• closed loop controlled spool position
• constant current actuator control with overcur-
rent shutoff
• excellent properties for response sensitivity and
temperature drift
•
differential input stage with various command
signal options
• diagnostic output for spool stroke
• standard central connection
• compatible to the relevant European EMC-
standards
