Scotch Yoke type pneumatic actuators usually refer to “single-cylinder double-piston-variable-torque fork type” pneumatic actuators, which are a range of piston-type actuators and are suitable for valves with a 90 ° angle (such as ball valves, butterfly valves, Stop valve or metering control).
AH-Series actuator may be easily altered from a single-acting to double-acting power cylinder configuration. And/or a hydraulic manual override may be added after the actuator has been in stalled
