Since its beginning in 1957, FLO-TORK has been recognized (or its original approaches to motion design technology and its ability to specialize in rotary actuator applications. These achievements have been made possible by a strong engineering staff that enables the company to custom design components-tailoring unique materials, tolerances and design specifications to each customer's needs. _ evolution and growth in military and industrial fluid power applications. In the mid-1980s FLO-TORK, Inc. recognized the need to diversify to continue its consistent growth philosophy. In analyzing its...

Choosing the correct actuator is as important as selecting the correct valve. The information offered below is presented in an effort to assist in the choice of the proper actuator for your application. If you are unsure of your selection and feel you need assistance, do not hesitate to contact your local FLO-TORK representative or the FLO-TORK Corporate office. Prior to beginning the actuator selection process it is necessary that you have the following information: 1) The maximum torque requ ired to break (unseat) the valve element from its fully closed (seated) position, against the...

SPRING RETURN FAIL CLOSE (CLOCKWISE) ACTUATORS NOTE: The SERIES M spring return torque charts are based on a clockwise spring stroke and provide the start (break), run (minimum) and end (closing) torque outputs for the spring stroke in addition to the pressure stroke output torques for the same positions of rotation. The spring break torque (highest spring output torque) is shown at the 90 0 position. This corresponds with the lowest pressure stroke output torque which is also at the 90 0 position. NOTE: The actuator output torque must exceed the maximum torque requ irements of the valve at...

NOTE: The torque chart values are minimum output based on ideal conditions. The actual torque output may vary based on adjustor stop screw position, alignment, service time between lubrication, & other influencing factors. *NOTE: Torque output exceeds model capacity at this pressure.
