A-T Controls TRIAC® SY Series scotch yoke actuators offer “workhorse” cycle operation. These robust multifunctional actuators complement the already reliable THD Series. The compact design provides options to meet your quarter-turn torque requirements.
The SY Series is a reliable way to automate quarter-turn valves and offers options for accessory mounting and manual override operation. The design is modular and allows for easy rotation choices. Simply rotate the actuator for clockwise (CW) or counterclockwise (CCW) operation.
This design features a supported scotch fork that is stabilized by significant body bearings for minimal wear. Multiple spring and pressure options let you achieve the torque balance you need. The increased efficiency in this design gives you the best actuator for the money.
For many applications, steel is simply better. These small scotch yoke steel actuators, compared to aluminum, offer better corrosion resistance in harsh environments such as marine saltwater and petrochemical applications. Additionally, surface coatings adhere better than aluminum. When your application demands robust and reliable valve actuation, count on the TRIAC® SY Series.
