ACTUATION

RCS Sure 65 

The Sure 65 Series Spring Return electric actuator is the latest expansion to the SurePower™ Spring-Return electric actuator product line. 

Product Features 

• Output torque of 780 inch-pounds (88 NM) and is available in either clockwise or counter-clockwise spring return on loss of power. 
• Typical Applications: For open / close and positioning control of: Quarter-turn ball, plug valves or rotary dampers when emergency shutdown or shutoff capability is required in the event of a loss of power. 
• ISO 5211 mounting configuration allows for direct installation without the need for mounting and adaption hardware. 
• Integral travel stops are provided for precise mechanical limitation of travel in the spring fail position. 
• The enclosure is suitable for installation in NEMA 4X and NEMA 6 environments (IP 66 and IP 67) 
• Actuator is CSA certified for NEMA 7 and NEMA 9 hazardous environments (Class I, Division 1 & 2, Groups C & D, and Class II, Division 1, Groups E, F, and G) and CSA Zone 1. 
• CSA NRTL/C Approved to UL Standard No. 429, Electrically operated valves. 
• CSA NRTL/C Approved to UL Standard No. 1203, Electrical Equipment for use in Explosion – proof and Dust – Ignition – proof Hazardous (Classified) Location. 
• ATEX Ex db IIB T5 Gb; Explosive gas atmosphere / Flameproof enclosure / Gas group IIB / Temperature code T5 / Zone. 
• ATEX and IECEx certifications are pending for both series. 
• The standard units are suitable for use in ambient temperatures ranging from -40°F to +150°F (-40°C to +65°C). Optional: -60°F to +150°F (-50°C to +65°C). 
• The powder-coated enclosure and stainless steel external hardware provides maximum corrosion resistance in the most challenging environments. Optional coatings are available for offshore or other severe conditions. 
• The integral power spring is coated for corrosion resistance and will provide reliable spring movement in case of primary power loss. 
• A high-visibility indicator is provided as standard for ease of visual position monitoring. 
• A thermally protected motor with Class “B” insulation is standard in all models, and is available in 120 and 240 VAC, 50/60 hertz. 
• Precision machined gears are machined from high strength alloy steel, and are heat treated for maximum strength and durability. The permanently lubricated gear train eliminates the need for periodic maintenance and upkeep. 
• Standard features include end of travel limit switches, 2 additional SPDT dry contact auxiliary switches, thermostat-controlled heater, and a motor brake for optimal performance. 
• Accessories such as analog and digital control modules, interposing relays, and potentiometers are available to tailor the units to specific process requirements. 
• The Sure 65 complies with the requirements of NFPA 130 & NFPA 502 for service in elevated temperatures of 482° F (250°C) for a minimum of one hour. 
• Pending: Optional integral declutchable manual override with electrical interlock.
