FEATURES
The well-accepted Pneumatic Cylinder Torque actuator is an actuator that gas made it possible to accommodate a variety of needs that continues to broaden, by accomplishing high power output, compactness and high dependability with accumulated improvements on the basis of rich experiences as well as performances.
Complete line-up is available from which optimum selection can be made for wider range of functions by combining with various accessories, for improved control capabilities or valve actuation in emergency.
With installation of manual override (optional) being possible, the dependability of any system can be further enhanced.
The Scotch-yoke mechanism produces a torque curve that most closely matches the requirements of valve actuation.
