Installation Instructions Document No. 129-186 September 25, 2009 Flowrite™ AP 599 Series 8-inch Pneumatic Valve Actuator Item Number 129-186, Rev. 300 Page 1 of 5 Product Description The Flowrite AP 599 Series 8-inch Pneumatic Valve Actuator is designed for use with the Flowrite VF 599 Series Valves with a 3/4-inch (20 mm) stroke. Product Numbers 599-01050 599-01051 Warning/Caution Notations WARNING Personal injury/loss of life may occur if a procedure is not performed as specified. CAUTION Equipment damage, or loss of data may occur if the user does not follow a procedure as specified. Required Tools 24 mm open-end wrench 30 mm open-end wrench 3/8-inch, 3/4-inch, and 1-inch open-end wrenches Expected Installation Time 55 minutes for field mounting of the actuator 90 minutes for removing the old and mounting a new actuator Prerequisites WARNING: If mounting the actuator to a valve already in line, either close the shut-off valves in the piping (upstream first, then downstream) or switch off the pump to allow the differential and static pressure in the valve to drop. CAUTION: Do not damage or scratch the polished surface of the valve stem. Figure 1. Acceptable Mounting Positions. The vertical position is recommended for mounting. The acceptable mounting positions are shown in Figure 1. Installation Begin with the instructions of Figure 6 if you are not replacing an existing actuator.

Spring Adjustment. Spring Adjustment The top edge of the stem nut indicates the valve stem position. The “0” marking on the actuator yoke indicates stem up position. The “1” mark indicates stem down position. See Figure 15 . With the actuator in an upright position and the stem visible as shown in Figure 15 , use a 3/4-inch open- end wrench to turn the adjustment screw. • For Normally Open Valves: To increase the start to close pressure, turn the adjustment screw from right to left. To decrease, turn the adjustment screw from left to right. • For Normally Closed Valves: To increase the start to open pressure, turn the adjustment screw from right to left. To decrease, turn the adjustment screw from left to right. NOTE: As the line pressure differential across the valve increases, the spring span will decrease. The installation is now complete.
