A scotch yoke actuator converts the straight-line movement of a pneumatic piston into a 90-degree turn using a sliding yoke. Its geometry gives the most torque at each end of the stroke and less in the middle, which suits valves that need high break-out and seating torque, such as large ball, plug and butterfly valves. The table shows this directly: torque is listed at 0°, 45° and 90°.
Two series are listed. The PD series is double acting: air pressure drives the piston both ways. Models PD45, PD50, PD55 and PD200 are shown with torque at supply pressures from 2.8 to 8 bar, and air consumption per stroke at 5.5 bar. The PDS series is spring return: air drives the actuator one way and an internal spring drives it back when air is removed, giving a fail-safe position. PDS models run from PDS-45 to PDS-200, with output torque up to 4,600 Nm, spring end torque listed separately, and ISO 5211 mounting from F05/F07 to F12/F16.
Filter by series, model and angle, then compare torque at your available air pressure with the valve's torque requirement. The series page lists ATEX and SIL capability; certification varies by model, so confirm it with Valvenok's UK team when you request a quote.
