TA2 Series（φ40～φ160）Pneumatic rotary actuator
■Extensive options：Many models with various options are now available as
standard.
They meet versatile requirements for total system establishment.
１．Electro-pneumatic Positioner ２．Switch box
３．NAMUR-compliant 5-port Solenoid Valves（Incorporating bypass valve）
４．NAMUR-compliant compact Size Explosion-proof Solenoid valve（Incorporating bypass valve）
５．FR Unit（Regulator with Filter） ６．Bypass Valve Incorporating Speed Controller
■Light weight and compact design：Employment of die-cast aluminum into main components and unique
body shapes achieves the lightweight and compact design.
■Oilless operation：High-quality lubrication-free materials are used as piston sliding packing and sliding
materials for bearing to maintain the high reliability in the non-lubrication operation.
■Spring cartridge：This system makes it possible to change the operation from single-acting type to
double-acting type and vice versa. The single-acting type is structured to obtain the same output torque
as that of the double-acting type in the air operation mode. (Patented)

TA200,TW250 Pneumatic rotary actuator
■Scotch yoke driving system
The scotch yoke mechanism which is compact yet allows high-efficient driving is employed. Both TA-200
and TW-250 exhibit the optimal torque characteristics for valve control requiring the maximum torque at
the rotation beginning and final ends.
■Abundant optional devices
Abundant optional devices have been standardized. The total system helps valve automatic operations.
■Connection method
The yoke or coupling-free direct mount system is employed for connection to valves.
・TA-200 employs a female angle conforming to ISO standards.
・TW-250 employs a female key socket system conforming to ISO standards.
