SY Series: Small Steel Scotch Yoke Actuator
SYSSSYA
Steel for Outstanding Corrosion Protection Pneumatic Actuators for Quarter-Turn Valves and Dampers Torques from 800 - 12,370 In-lbs. Double Acting Spring Return TRIAC® SY Series scotch yoke actuators by A-T Controls offer “workhorse” cycle operation. These rugged multi-purpose actuators are the compliment to the already trusted THD Series. The compact design offers options to address your quarter turn torque requirements. The SY Series is a reliable way to automate quarter turn valves and provides options for accessory mounting and manual override operation. The design is modular and allows for easy rotation choices. Simply flip the actuator to achieve clockwise (CW) or counterclockwise (CCW) operation. This design features a supported scotch yoke which is stabilized by significant body bearings for minimal wear. Various spring and pressure options allow you to achieve the torque balance you need. Increased efficiencies in this design give you the most actuator for the money. For many applications, steel is just better. These small steel scotch yoke actuators, compared to aluminum, provide better corrosion resistance in harsh environments such as marine salt water and petro-chemical applications. Additionally, surface coatings adhere better than aluminum. When your application calls for rugged and reliable valve actuation, rely on the TRIAC® SY Series

The THD series is designed to operate ball, butterfly, plug valves, dampers or any device that requires a quarter-turn movement for on-off or throttling service. Our standard offering is the symmetrical design yoke that delivers maximum torque at both ends of the 90º cycle. The square slide bearing with guide bar provides high cycle life and smooth stroke while minimizing wear points. Also available is a canted yoke design, which is ideal for butterfly valves in sizes C11 and larger. As with all TRIAC® actuators, our THD series is accompanied by a complete line of accessories, including jackscrew and hydraulic overrides, limit switches, solenoids and positioners. A-T Controls also offers complete mounting hardware to integrate our actuators with any quarter-turn valve, damper or louver.

TRIAC® Floor Mounted Damper Drives Available in Pneumatic or Electric Configurations
TriacFMDD
TRIAC® floor mounted damper drives are the best choice for operating dampers, vanes and fan control where high vibration, heat, extreme cold, dust and inaccessibility render direct coupling of actuators to shafts impractical. Available in pneumatic (on-off and modulating), and electric (24 VDC, 120 VAC 1-phase, 220 and 440 volt 3-phase configurations, these rugged drives combine industry proven TRIAC® pneumatic and electric actuators with our engineering expertise. The rugged frames can be ordered to dimensionally replace older drives manufactured by several previous suppliers. TRIAC® frames consist of welded steel housings with pillow block bearings, maintenance access panels, and our unique infinite position lever arms. The units are tough enough for the harshest environments found in today’s refineries, power plants, steel-making boiler rooms, water treatment facilities, pollution controls, pulp and paper industries and co-generation turbine units. Contact A-T Controls for specific drawings and specifications for your replacement or new applications.
