Pneumatic Rotary Actuators

TA-200 & TW-250 Series Rotary Actuators (φ200，250)


	TA-200 & TW-250 Series Rotary Actuators (φ200，250)

Pneumatic rotary actuator suitable for automatic open/close operation of valves with large diameter.

Scotch yoke driving mechanism

Compact size employing scotch yoke mechanism that allows highly efficient operation.

Both TA-200 and TW-250 offer excellent torque function suitable for controlling a valve that needs optimal torque at end of rotation.　

Abundant optional components

Many models with optional components are now available as standard to meet demands for comprehensive automatic valve control system.

Mounting

Direct mounting without yoke or coupling.

TA-200 is female type complying with ISO standards.

TW-250 is female type complying with ISO standards with key socket.
