FEATURES AND BENEFITS
* Innovative stainless steel
hh strength 17-4PH stainless output shaft
transmits torque and gives long service life.
Heat-treated stainless steel thrust pin and
rollers transfer piston force to yoke to reduce
riction for longer life and more efficient
torque transmission.
Bi-directional travel stops provide accurate
valve rotation adjustment.
PTFE piston bearings, piston rod bushings
and output shaft bushings provide longer
ife, reduce maintenance and require no
ubrication.
Universal design position indicator and
pointer allows for either parallel or
perpendicular mounting.
Stainless steel construction allows proximity
switches to be direct-mounted in the actuator
housing, eliminating the need to mount
bracket and cam assemblies on top.
* NAMUR drive slot maintains a compact
assembly for accessory-driven components
with no couplings necessary.
* Available in symmetrical and canted yoke
design to suit application.
* Spring return model design requires no
special tools to disarm springs safely and
easily, reducing down time.
