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.
