VESON VSF heavy duty scotch yoke actuator product line offers a broad range of torques to 1,600,000 in-lbs. VESON VSF 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 different sizes and larger.
