This range of valves has an optoelectronic encoder and
microprocessor-based control that carries out all functions to
enable the user to control the valve at all times. The high
speed microprocessor accommodates many functions
including:
•
Automatic initialisation
•
Intelligent port alignment
•
Manual switch debounce
•
Selectable format position output code
•
Reset facility
•
RS232 interface
A primary function of the microprocessor is to provide excep-
tional alignment between the fluid paths of the rotor and valve
body. This is achieved by the constant monitoring and minute
adjustment of the valve position throughout the life of the valve.
All of the valves may be actuated in either direction and
programmed to stop at any combination of ports to provide
maximum versatility.
