CONTROL
Analogic proportional servo valves
Positioning control - Series LRXA4
3/3-way servo valves which control the positioning of pneumatic
cylinders
LRXA4 servo valves are proportional
valves with a high-precision integrated
control for the positioning of pneumatic
cylinders. The valves include a patented
3-way system based on the rotating
spool principle with electronic control of
the spool position.
The servo pneumatic closed loop system
allows, through the feedback of the
external positioning sensor, the control of
position, speed and acceleration.
The electronic board is directly integrated
in the valve body.
Through the use of a proper connector,
the Master valve mod. LRXA4 is
connected to a second LRWA4 valve
that will work as a slave-valve.
