General Model 1098-EGR
Type Double-Acting Scotch-Yoke Rotary Actuator
Product Line RCS Classic
Performance Torque Output The "E" in EGR specifies the actuator size, which determines its torque output. For size "E", the torque is approximately 900 lb-in (102 Nm) at an 80 psig (5.5 bar) supply pressure.
Standard Rotation 90° (Standard). Other angles are available.
Supply Pressure Typical operating range: 40 to 120 psig (2.8 to 8.3 bar).
Action & Options Action The "GR" portion of the suffix defines the standard package. As a double-acting actuator, it requires air pressure to move in both directions and has no spring return.
Positioner Mounting The "GR" package typically includes a bracket and linkage ready for the installation of a Fisher 1061 or similar pneumatic positioner.
