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.

Fig. 4. Attaching the stem connector screw

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

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.
