Flowrite™ 8-inch Pneumatic Valve Actuator Technical Instructions Document Number 155-161P25 June 14, 2019 Operation 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. Mounting and Installation Allow 12 inches (300 mm) headroom and six inches (150 mm) on either side for servicing the actuator.
