LRWA0 SERVO VALVES - PNEUMATIC INSTALLATION
The servo valve works as follows: if the command signal or setpoint is lower than 50%, the valve establishes a link between
connection 1 and connection 2; then the air passes between the inlet and the outlet. If the setpoint value is higher than 50%, the port
2 is connected with the exhaust 3. For a better understanding, please see the flow diagram on page 2.15.11.2.
THE LENGTH OF THE LEADS SHOULD BE AS SHORT AS POSSIBLE, BETWEEN VALVE-OUTLET AND LOAD NORMALLY
NOT MORE THAN 2 mts.
