General Application

The Hytork™ XL-Series Rack and Pinion actuators are intended
for the automation and operation of quarter-turn valves like
Butterfly, Ball and Plug valves.
Rack and Pinion actuators can also be used to operate venting
louvers or any other quarter-turn applications.
This product was intended for a specific range of service
conditions: pressure, ambient temperature, operating media
and possibly other specifications. Do not expose the product to
service conditions or variables other than those for which the
product was intended.
If you are not sure what these conditions or variables are, contact
your Emerson sales office for assistance. Provide the product
type, size, serial number and all other pertinent information that
you have available.

Inspection and Maintenance Schedules

The Hytork XL-Series Rack and Pinion actuators must be
inspected periodically and maintained as needed. Refer to
Installation, Operation and Maintenance Manual, MAC050515 EN
for more detailed information.
The schedule for inspection can only be determined based
on the severity of your service conditions. Your installation
might also be subject to inspection schedules set by applicable
governmental codes and regulations, industry standards,
company standards or plant standards.
In order to avoid increasing dust explosion risk, periodically clean
dust deposits from all equipment.
When equipment is installed in a hazardous area location
(potentially explosive atmosphere), prevent sparks by proper tool
selection and avoiding other types of impact energy.
Proper care must be taken to avoid generation of static
electricity on the non-conductive external surfaces of the
equipment (e.g., rubbing of surfaces, etc.). The actuator's surface
temperature is dependent upon process operating conditions.
