ACCESSORIES
Extension Yokes
The extension yoke (see also Fig. 7) provides for extra air
circulation and less conduction of heat from the valve body to
the pneumatic actuator.
Recommended if the medium temperature in the valve body
is in the range of from 150 to 220 °C.

TYPICAL OPERATION
In a direct-acting (normally-open valve) system, an increase
in control air pressure will force the actuator diaphragm and
cup downward, forcing the valve stem down to proportionally
close off the flow through the valve.
Operators without the positive positioner have branch line
pressure applied to the diaphragm. Operators with positive
positioners have up to full main air pressure applied to the
diaphragm to ensure that the valve is positioned
proportionally to the branch line pressure.

INSTALLATION
General
Ensure that the actuator has the correct size and travel to
match the valve body. Refer to the corresponding valve
product literature.
Mounting the MP953A,C (Size 5")
1. Pull the valve stem up.
2. Position the stem-locking slide so that the large hole is in
view (see also Fig. 3).
3. Set the actuator on the valve bonnet. Ensure that the stem
button passes through the hole in the stem-locking slide
and that the actuator is down flush on the shoulder of the
valve bonnet.
4. Rotate the actuator on the valve bonnet to the desired
position and tighten both actuator set screws.
5. Apply air pressure until the diaphragm cup contacts the
stem button and secure the stem button with the stem-
locking slide.
Mounting the MP953A,C (Size 8" and 13")
1. If converting from smaller-size actuator, remove the
actuator by following, in reverse order, the steps outlined
in section "Mounting the MP953A,C (Size 5")".
2. Remove the stem button (see also Fig. 5).
3. Screw the stem button on the (single or double) stem
extension until it bottoms.
4. Screw the stem extension on the stem until it bottoms
(flats or locking-pin hole provided).
5. Rotate the stem extension as required to adjust dimension
"Y" as per Table 5 to the value listed, then lock the stem
extension in place by tightening the hex nut.

Mounting the MP953B,D
1. Pull the valve stem up.
2. Attach the stem connector screw to stem button (Fig. 4).
3. Place the actuator on the valve without pushing the stem
down.

4. Turn the stem connector screw by its screw-slot
counterclockwise to back out the stem button until the
actuator is in contact with the shoulder of the stem button.
5. Push the actuator onto the valve bonnet and hold it firmly
in place; tighten the two set screws
6. Load the stem by turning the stem connector screw
clockwise by its screw slot.
a) On a straight-through valve (position 1), turn the stem
connector screw until a clearance A of approx. 3 mm
(1/8") exists between the spring and the actuator
spider.
b) On a three-way valve, a clearance A and B of approx.
1.5 mm each is required at both ends of the stroke to
permit proper close-off. If there is no air on the
actuator, adjust the A clearance approx. 1.5 mm and
recheck the B clearance when air is available.
7. If clearances A and B cannot be adjusted following the
procedure outlined above, check the stem height "y" and
adjust, if necessary.

ADJUSTMENTS
NOTE: Adjustments are necessary only for the
GRADUTROL-Relay used with the MP953A, B.
The range is adjusted using six adjustment screws (see also
Fig. 6). Note label on body of GRADUTROL-Relay. All
devices are factory-set for 35 kPa range. This point is ad-
justed by turning the adjustment knob. The graduations of the
external calibration scale on the knob present various values
within the different ranges. All devices are factory-set for
35 kPa start point. After completing the adjustment pro-
cedure, do not change the position of GRADUTROL-Relay
(with respect to the actuator).

One graduation of scale on the start point adjustment knob represents a

One graduation of scale on the start point adjustment knob represents a
start point change of 2 kPa. Three complete turns of the start point

One graduation of scale on the start point adjustment knob represents a

Adjustment Check
1. Install a gauge in the pilot air line (P).
2. Adjust the set screw (see Fig. 6) so that travel just begins.
3. Increase pilot pressure (P) until travel is complete. If the
adjustment is correct, the gauge should read this pressure
within ±5 kPa of the start point pressure plus the range
setting.
EXAMPLE: Range setting 35 kPa start point setting 21 kPa.
The gauge should then read 56±5 kPa after the travel is
completed.
4. If the measured pressure should not be within the
permissible variation, fine adjustments must be done (if
necessary) using the start point adjustment knob.
MOUNTING WITH EXTENSION YOKE
For working temperatures of 150 to 220 °C (300 to 425 °F),
use of an extension yoke is mandatory for the MP953A,C (5"
and 8") and the MP953B,D actuators to protect the diaphragm
against excessive heat. Screw the stem extension (for the 5"
size) onto the stem, with the stem either pulled out or pushed
in (see Fig. 7), and adjust dimension "y" to the value listed in
Table 6. Lock stem extension into place by tightening the hex
nut, and attach the yoke.
