Features

  • The integral mounting pad eliminates the traditional mounting bracket and reduces the number of parts required to mount.
  • Incorporates an integral air passage that eliminates the need for external tubing and fittings when paired with a Fisher FIELDVUE™ instrument.
  • Both 657 and 667 actuators are compatible with instruments that utilize traditional bracket-based mounting kits. The 667 can be externally tubed for instruments or accessories when required.
  • Spring rates, travel stops, and manual operators are available for nearly any control valve application.
  • A molded diaphragm travels in a deep diaphragm casing, minimizing area change throughout the travel.
  • A shallow casing on the pressure side means reduced volume on that side, thereby minimizing response time.
  • The molded diaphragm allows maximum thrust for given diaphragm size.
  • Rugged thick-walled cast iron and steel construction provides increased stability and corrosion protection.
