Refer to the corresponding valve product literature. Mounting the MP953A, C (Size 5") 1. Position the stem-locking slide so that the large hole is in view (see also Fig. [. . . ] 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. 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. If clearances A and B cannot be adjusted following the procedure outlined above, check the stem height "y" and adjust, if necessary.

Attach the stem connector screw to stem button (Fig. Place the actuator on the valve without pushing the stem down. 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. All devices are factory-set for 35 kPa range. This point is adjusted 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 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. [. . . ] EXAMPLE: Range setting 35 kPa start point setting 21 kPa. The gauge should then read 56±5 kPa after the travel is completed. If the measured pressure should not be within the permissible variation, fine adjustments must be done (if necessary) using the start point adjustment knob.

Screw the stem extension (for the 5" size) onto the stem, with the stem either pulled out or pushed in (see Fig. [. . . ]
