Пневматические приводы AW серии

1. Overview AW pneumatlc actuators are divided to double-acting and single-acting (spring return ) with two separated cylinders and double pistons. It is easy to make actuator with huge size cylinder and output torque by this design;lnner of cylinder and piston axis are coated with hard chromium that has good anti-friction. The output torque of AW actuator is good for opening, closing and adjusting of big size ball valves & butterfly valves. meanwhile it fits 90 degree rotary occasion. 2. Technical data Genera l DesignPneumatic Double-Cylinder Double-Piston Shifting fork Type Actuator; Model AW Means Double-Acting; Model AWS Means Single-Acting Spring Return. Rotary AngleDouble-Acting 90°; Single-Acting 90°; Adjusted from -5° +5° from two ends. Operating Temperature-20°C 90°CAir supply Pressure0.3 0.7MPa. 3. Model Number 4. Actuator Selection & Installation When select the actuator, the torque of valve must be identified firstlγ, then consider the fluid; Add 25% security value when it is steam or non-Iubricated; Add 60% security value when it is non-Iubricated dry gas media; Add 100% security value when it is non-Iubricated gas transmission particles media; Add 20% security value when it is clean and no friction lubrication media; Then check the double-acting or single-acting type torqueform according to air source pressure, and the model of actuator can be chosen correctly. 5. Actuator & Accessory Function Double - acting pneumatic actuator;Double position control of valve's open or close Spring Return: Valve open or close automatically when circuit ,gas is cutoff or failure (Explosion-prool offer available) Single-control solenoid valve: Valve opens or closes when power on , vice versa(explosion-proof offer available) Double-control solenoid valve: Valve opens when one coil is power-on. Valve closes when another coil is power-off. It has memory-savefunction (explosion-proof offer available) Limit Switch 60x: Long -distance transmission of valve position signal (explosion-proof offer available) Electric Locato r: Regulate and control the flow of media accord ing to current signal (Standard 4-20mA) (explosion-proof offer avai lable) Pneumatic Locator; Regulate and control the flow of media according to pressure signal IS tandard 0.02- 0.1MPa) Electrical Converters: It converts current signal into pressure signal, and used with pneumatic locator (explosion-proof offer available) Air Source Treatment Triple-Unit: It includes pressure reducer , filter, oil mist and has air pressure -stability,air source - cleaning ,parts - lubrication functions Manual Operation Institutions: It can be manual operated if automatic operation is out of control 6.
