Actuator price Introduction锛?/strong The pneumatic actuator developed and manufactured by Hiton,it is a kind of crank arm piston type, compressed air forces piston to move linearly through the cylinder, and linear movement can be transformed into quarter turn rotation through the crank arm. The actuator has a high precision of rotation, small return difference and dead range of output torques and complete models which are used in control system of quarter turn on/off valves. It is a multi-fuctional actuator, which is suitable for almost all range of quarter turn valves. Features: High precision of rotation All rotation area are equipped with high precision bearings. Long service life For small size actuators, its cylinder material is aluminum alloy, inside surface with special anti-abrasion treatment, piston rod with hard chromium coated and mirror finish grinding, piston with guided ring and dual sealing design. Strong impact resistance Crank arm is in integral casting construction which has high strength,good stability and strong impact resistance. Easy to adjust,and large adjustment range Through the 2 adjusting screws located on 2 sides of the actuator,it is very easy to adjust the stroke of the actuator,in a range between plus 10 degree to minus degree. Excellent safety performance For single acting pneumatic actuator, it is with spring anti-blowout design, enable the use of actuator becomes safer. Selection can be more flexible,economical and practical Body and cylinder assembly can be incorporated according to torque requirement,which provide small level different of output torque levels. So the selection is more flexible. Achieve quick open/close Incorporated with pneumatic accessories,it can achieve a quick open or close. With changeable torque output feature, it is closer to the real requirement that valve had been used in service The output torque at open starting point is the highest, which exceeds the nominal rated output torque, so safety factor is higher. Selection of double acting actuator This series of actuators are suitable for quarter turn valve,follow the below steps to choose the actuator. 1. Confirm the valve type is belonged to quarter turn valve. 2. Confirm the required valve stem torque. 3. To select a suitable actuator, generally the rated output torque of selected actuator shall be 1.1 to 1.3 times that of valve鈥?s stem torque, which also depends on the importance of the valve. If it is required with high reliability for the valve operation, then an actuator with more safety factors shall be selected. 4. Pay special attention to the air supply pressure at jobsite, it is important to select a correct actuator based on the real air supply pressure.Actuator price website:http://www.hsv-valve.com/actuator/
