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 position.

Figure 2. Acceptable Mounting Positions.
Allow eight inches (200 mm) headroom and six inches (150 mm) on either side of the
actuator.
For best performance, install the actuator vertically above the valve. The actuator can
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 2 for allowable mounting positions.
Complete instructions for field mounting the actuator are included with the actuator.
The “0” marking on the actuator yoke indicates stem up position. The “1” mark indicates
stem down position. See Figure 1.
