Product Numbers
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. This actuator is available
with two diaphragm options.
• Completely enclosed actuator housing protects the diaphragm, spring, and start
point adjuster.
• Positioning relay is available factory mounted or as an accessory.
• Start point of the actuator spring is adjustable. This allows the valve to be
sequenced.
• Easy installation.
These 8-inch actuators are designed to be used on Flowrite VF 599 Series valves in
liquid service and steam service applications.

Operation
Mounting and
Installation
The control air signal upon the diaphragm causes the valve to modulate whenever the
air pressure is within the spring range of the actuator. The actuator spring provides the
necessary force to hold the stem in the stem up (direct acting) position.
Allow 12 inches (300 mm) headroom and six inches (150 mm) on either side for
servicing the actuator.
For best performance install the actuator vertically above the valve. The actuator may be
installed in any position between vertical and horizontal. Siemens Building Technologies
does not recommend installing the actuator below horizontal or up side down. See
Figure 1 for allowable mounting positions.
Complete instructions for field mounting the actuator are included with the actuator.
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 2.

Spring Adjustment
With the actuator in an upright position and the stem visible as shown in Figure 2, use a
3/4-inch (.75 mm) open end wrench to turn the adjustment screw.
• 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.
• 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
decreases.
