fail-safe operation.
Applications include:
• Volume control dampers, mounted directly to the drive
shaft or remotely (with the use of accessory hardware).
• Quarter-turn rotary valves, such as ball or butterfly valves
mounted directly to the drive shaft.
• Linear stroke globe or cage valves mounted with linkages
to provide linear actuation.
