1.2.Product description and application
1500 series intelligent valve positioner is a valve stroke controller based on
microprocessor. The valve stroke can be set by external input signal. The
positioner can adjust valve stroke quickly and accurately by using automatic
control algorithm and PWM control technology. The product can be used in
sealed space and controlled automatically and remotely. It is easy to install,
operate, maintain and has low failure rate.
The positioner can combine with different pneumatically actuated valves for
using. As shown in Figure 2.

2.2.Actuator combination
2.2.1. Actuator of line stroke
1. Make sure that the stroke range and the screw thread size of the actuator
which needs to combine meet the requirements.
2. Separately measure the C1 value when the valve is fully closed and C2
value when the valve is fully open by the depth ruler. The values are the
distance between the stem top and the datum clamp face of the actuator.
As shown in Figure 5.
Valve is fully closed Valve is fully open

3. Adjust the adjusting nut of the displacement sensor. Then measure the D
value (as shown in Figure 6) by the depth ruler in the state of the
displacement sensor being completely loosened. Calculate the compr-
ession value L1 = D –C1, L2 = D –C2. It is recommended that the
compression value L1 and L2 are both in the reference range which is
showed in Table 1. If L1 value or L2 value is unable to meet the reference
range, adjust the D value according to the actual situation.

4. Raise the internal valve stem of the actuator to the highest position. Make
the actuator connection of the positioner entering into the thread
connection of the actuator by NO.32 wrench. As shown in Figure 7.
The adjusted D value must ensure that L1 ＞0, L2 ＜the maximum
compression value of the displacement sensor. Otherwise, the positioner
cannot match the actuator.

5. Power up the positioner, adjust the valve position manually and run the
auto-tuning function in the initial mode. Check that whether the whole valve
stroke range is in the effective range of the displacement sensor (Refer to
the Chapter 5 Section 5.2.1 and Section 5.3.1 for details.). If not, repeat
step 3.
2.2.2. Actuator of angle stroke
1. Fix the mounting body under the positioner. As shown in Figure 8.
2. Connect the feedback pole of the positioner with the axis of the actuator.
As shown in Figure 8.
