For
REVERSE ACTING valves (RA=air opens),
Figure 2000 RA
do as above.
The procedure is also valid for 3-way valves 2600 RA
– 2700 RA – 5700 RA
For example, if the signal planned is 3-15 psi, the valve must start to move at 3 psi and at 15 psi it must have executed
the entire stroke, reaching total opening.
If the start signal is under 3 psi, you must:
- loosen the nuts ref. no. 20 tightening the upper stem no. 22 with the lower stem ref. no. 6.
- unscrew the lower stem ref. no. 6 to increase the start signal.
If the start signal is over 3 psi, you must:
- loosen the nuts ref. no. 20 tightening the upper stem no. 22 with the lower stem ref. no. 6.
- screw in the lower stem ref. no. 6 to reduce the start signal.
“2000 RA”
Attention!
During the calibration phase, ensure
the valve executes the full stroke.
This operation can be visually inspected by
observing the indicator plate ref. no. 21 sliding on
the indicator label ref. no. 19.
Repeat the opening/closure or closure/opening
operation until the right values are obtained.

– ON-OFF PNEUMATIC VALVES
On-off pneumatic valves are supplied already calibrated according to the control signal, chosen by the client, and based
on the input pressure of the fluid. On-off valves do not require any calibration control operations.
