Screw the stem extension on the stem until it bottoms (flats or locking-pin hole provided). 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. 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.

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. 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. 1. 5 mm each is required at both ends of the stroke to permit proper close-off. 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 graduations of the external calibration scale on the knob present various values within the different ranges. After completing the adjustment procedure, do not change the position of GRADUTROL-Relay (with respect to the actuator). stem button connector clearance "B" (measured when spring is compressed) clearance "A" set screw Fig. Attaching the stem connector screw 3 EN0B-0552GE51 R1009 Y3 with stem extension for MP953A, C 13" MP953A, B, C, D PNEUMATIC ACTUATORS set screw operating range 70 kPa (10 psi) range adjustment ALL screws "1" and "2" tightened.
