SERIES SURE 100
Electripowr TM Type
SR
1200 Inch Pound Torque Output
The SURE 100 is the largest and latest model of the RCS - Surepowr
Series Spring Return Electric Actuators. This newly-developed product
incorporates the most advanced high-tech research and design, yet it
uses a simple concept-a torsion power spring which provides - dependable
mechanical force for actuation when electrical power is lost. The Sure
100 torque capability is ideally suited for industrial-grade dampers and
rotary valves when emergency shutdown ;s required. This model is
available in two speeds for two position (open/close) control as well as
modulating control service. The Sure 100 enclosure complies with NEMA 4,
7 and 9 requirements and is available with either clockwise or
counterclockwise power spring drive. CSA certification is in progress.
Applications
 | Safety shutdown for automated
and computer-controlled systems
| Used where emergency shutdown is
required in critical valve applications, such as 6" and 8"
butterfly valves, 2" and 3" ball and/or plug valves
Process control systems, all types
Vapor recovery systems
Tank truck loading station
| For fast and accurate closure of
dampers in air systems that require reliable emergency operation
Vehicle tunnel and subway station smoke exhaust systems
Power plant coal dust collecting systems
Air intake and exhaust ventilation systems for electric utilities
Isolation dampers for air handling systems in energy plants
Dryer systems
| Used in combination with RCS
Digi-LineTM Solid State Positioners to perform a wide range of
precision control functions Will automate power switches and safety
devises
| Will Automate power switches and
safety devices |

Features
| Powered by a rugged,
high-torque, integral, 115 Vac or 220 Vac 50/60 Hz, single phase,
reversible motor
| Precision-cut gears and shafts
are heat-treated high alloy steel
| High Visibility position
indicator
| Designed for intermittent and
modulating service as typified by applications which require
emergency operation to a pre-determined position
| Unique micro-adjustment plates
permit fast, accurate setting of travel limit switches when needed.
Switch activating cams are independently adjustable throughout the
actuator 90¡ rotation for maximum setting flexibility and accuracy.
Built-in motor overload protection
Gear train designed to withstand stall torque
Operates in any attitude or position
| Accessible, clearly-marked
integral terminal strip assures fast, easy field wiring
| Two 3/4" NPT conduit
entries
| Adjustable end-of-travel stops
| ISO 5211 mounting dimensions
| Electroless nickel plated output
configurations provide maximum corrosion protection |
