AW series large-torque pneumatlc actuator

Its scotch yoke structure makes piston rod move from linear to rotary.Special U-type output torque structure is used for valve opening or closing,which needs large torque.The structure is novel and flexible.It can generate 50% torque than common rack and pinion pneumatlc actuator.It is suitable for large and medium size valves and is widely used in automatic and remote control operations.

.Piston air chamber is sealed and separated from scotch yoke mechanism.Air consumption is small.
.The two cylinders input air at the same time,which leads to homogeneous pressure,large output torque and steady action.
.Double direction stroke limit.Rotation can be adjusted ±5°
.Output shaft(or indicator) can indicate valve opening and closing position.
.Bottom connection is according to ISO5211 standard.
.Material is nodular cast iron(QT450-10).High strengh.
.Top is fit for mounting all kinds of electric and pneumatic accessories.
.Product Model  13 / 17 / 20A / 20B / 25 / 28 / 35 / 40 / 50 / 60 / 70 / 80
.Output Torque  430 ~18WN*M
