Introduction |
I. Actuator Body |
Boy material is alumina alloy. Internal and external surface are treated with anodize oxidation and polishing. Outer surface is nickle plated so that the anti-corrosion fiction of actuator and minimum friction against pistons can be guaranteed. |
II. End Cover |
End cover material is die-casting aluminum End cover is treated with epoxy polyester so as to best guarantee the anti-corrosion performance. |
III. Drive Shaft |
The drive shaft material is medium carbon steel with fine processing and nickle plating so that the pistons have better quality in anti-corrosion, anti-friction, etc. |
IV. Piston |
Piston material is die-casting aluminum alloy. Maximum torque can be output when the actuator is actuated with certain pressure. |
V. Piston Seal |
NBR-70 rubber sealing is applied to ensure the normal and reliable performance of actuator under normal temperature. FPM can be also applied according to clients' requirements. |
VI. Travel Adjustment |
Plus/Minus 5 degree travel can be adjusted through the two bolts. |
Application
Pneumatic Rotary Actuators can be suitable for various flammable, corrosive, duty, strong magnetic field, radiation, vibration corrosive environments indoor or outdoor, which are widely used in the field of electric power, petrochemical, metallurgy, petroleum, gas, town, construction drainage, chemical industry, oil refining, mining, power plant, metallurgy, architecture, medicine, food, gas, scientific research, etc.
