Section 1: General
HQ Series electric actuators are design to provide reliable and efcient operation of 90°
quarter-turn valves, dampers, etc.
! WARNING
Use caution when working in, with, or around valves and actuators. High pressures, forces,
voltages and ammable media can be present.
! WARNING
Failure to follow instructions for proper electrical wiring, storage, set-up and maintenance
may cause serious injury, damage equipment, or void warranty.
1.1 Pre-Installation Inspection
Verify the actuator nameplate to insure correct model number, torque, operating speed,
voltage and enclosure type before installation or use. It is important to verify that the
output torque of the actuator is appropriate for the torque requirements of the valve and
that the actuator duty cycle is appropriate of the intended application.

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.
