This range of valves has an optoelectronic encoder and
microprocessor-basedcontrol that carries out all functions to
enable the user to control the valve at all times. The high
speedmicroprocessor accommodatesmany functions
including:
•
Automatic initialisation
•
Intelligent port alignment
•
Manual switchdebounce
•
Selectable format positionoutput code
•
Reset facility
•
RS232 interface
Aprimary functionof themicroprocessor is toprovide excep-
tional alignment between the fluidpaths of the rotor and valve
body. This is achievedby the constantmonitoring andminute
adjustment of the valveposition throughout the lifeof the valve.
All of the valvesmay be actuated in either direction and
programmed to stop at any combinationof ports toprovide
maximum versatility.
