Section 2: Actuator Mounting
Do not lift the actuator by the handwheel.
The actuator may be mounted in any position. The HQ-Series actuators are supplied
with a female drive output, ISO5211. Bolt patterns are provided for actuator mounting.
The actuator drive bush is removable for ease of machining.
It is mandatory that the actuator be rmly secured to a sturdy mounting bracket or directly
mounted to the valve’s ISO mounting pad. High tensile bolts or studs with spring locking
washers must be used. The valve output shaft must be in line with the actuator output
drive to avoid side-loading the shaft. To prevent backlash, no exibility in the mounting
bracket or mounting should be allowed.
