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 stemlocking 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.
