After completing the above instructions, the valve linkage must be adjusted in accordance with
the following procedure:
Adjustment Of Auto-Stop Valve
Before any adjustment of the valve is made, be sure that the Preset setting wheels indi-
cate a quantity other than zero to insure that the trip mechanism of the register is in proper
position.
To Adjust Valve Linkage
1. Depress the emergency stop button on the register and turn the shaft (O) clockwise.
2. Assemble register arm (N) on knurled knob in position as shown for specific assembly. (See
Fig. 4). Arm should move an equal distance each side of vertical center line (M) (Angle x = x).
3. Assemble valve arm (H) as shown for specific assembly. On the right hand assembly there
must be one notch between the cast mark (K) on the valve arm and the cast mark (J) on the
stop plate (J above K). On the left hand assembly these cast marks must be in line.
4. Assemble one nut (P) on connecting rod (G) and assemble clevis to the other end of the
connecting rod a distance of 1 ″ .
5. Insert end of connecting rod through register arm link and assemble clevis (F) to valve arm
(H) using upper hole. (See Figure 4). Insert clevis pin (E).
6. Open valve all the way. The opening of the valve is stopped by the set screw (B) which should
project approximately 1 ⁄
8
″
below the lug holding it. Turn shaft (O) counterclockwise to latch up
mechanism. With valve held open, tighten nut (P) against register arm link. Then assemble
and tighten second nut at (P).
7. Depress the emergency stop button and allow the valve to close. At this point the linkage
between the valve and the register must be free. If it is not, the above adjustments must be
rechecked.
8. Set the register to deliver the minimum quantity and open the valve to run product through
the flowmeter.
9. After the initial trip occurs the valve should close to the intermediate flow position. This rate
should be approximately 15 to 20 gpm. If the valve closes too far, or all the way, unscrew
clevis (F) on rod (G) to hold valve open further. If the rate of flow is too fast during the
intermediate position, turn the clevis onto the rod to allow the valve to close further. It should
not be necessary to turn more than one turn in either direction.
