China Actuator manufacturers Features 鈼?Mounting to valve either directly or via bracket. 鈼?Conforming to European and International Standard EN ISO 5211, preferred dimensions. 鈼?Double rack & pinion design. 鈼?Double acting or Spring return models utilize the same compact body design. 鈼?Aluminum body, hard anodized externally and internally, for corrosion and wear resistance. 鈼?Adjustable travel stops. 鈼?Safe end cover bolting requiring no special tools. 鈼?Anti blow-out drive pinion. 鈼?Namur air connection can be easily mounted with solenoid valve. 鈼?Parallel and diagonal, double square(star) drive. 鈼?Travel adjustment (at each end) 卤5掳. 鈼?Easy field conversion between DA and SR models. Technical data TorqueSpring return 3.4 - 2442 Nm Operating mediumAir (dry or lubricated) Travel adjustment(at each end) 卤5掳 TemperatureStandard -20掳C to +80掳C Low temp. -40掳C to +80掳C High temp. -15掳C to +150掳C Air supply pressure2.5 bar (36 PSI) to 8 bar (116 PSI) Spring return operation function (standard rotation) TOP view: 鈼?Air supplied to Port 2 forces the pistons apart and toward the actuator end caps, compressing the springs with the exhaust air existing at Port 4, a counter clockwise rotation is achieved. 鈼?On loss of air pressure (air or electric failure) at Port 2 allows the springs to force the pistons together with the exhaust air exiting at Port 2, a clockwise rotation is achieved. Double acting operation function (standard rotation) TOP view: 鈼?Air supplied to Port 2 forces the pistons apart and towards the actuators end caps, with the exhaust air exiting at Port 4, a counter-clockwise rotation is achieved. 鈼?Air supplied to Port 4 forces the pistons together with exhaust air exiting at Port 2, a clockwise rotation is achieved.China Actuator manufacturers website:http://www.fluid-valvestech.com/actuator/
