Scotch Yoke Heavy Duty Pneumatic Actuator
I. This series of pneumatic actuator applies replaceable bearings, highly efficient wear and corrosion resistant coating system, and tension rod compressed spring. Modular design improves efficiency, reduces wear, extends life. Available in symmetric or canted yoke.
This series is available for rugged subsea service with diver or ROV intervention systems at virtually any water depth. These actuators are well suited for riser and other fail-safe applications.
This eries actuators are uniquely constructed and have undergone a rigorous testing and qualification program to validate and document product performance for use within the containment and safety-related areas in nuclear service.
II. Available for operating temperature -40° C to + 66° C (-40° F to +150° F)
III. Operating pressures are pneumatic 3-14 bar (40-220 psig), hydraulic to 345 bar (5, 000 psig).
IV. Key Features
Pair with ball, butterfly, plug valves, and other quarter-turn devices.
