Single acting pneumatic actuator and double role is what mean

Double-acting pneumatic actuators is you to start turning, open the valve, when to close the valve, on the other side to give up is needed to shut down! And single action is you give spirit cannot open to air is automatically shut down! Next we know about the single acting pneumatic actuator and the working principle of the double-acting actuators. The selection of actuators with double acting actuators with double acting in DA series pneumatic actuators, for example. Gear actuator output torque is piston pressure ( Air pressure supplied) On the pitch circle radius ( Arm) Income, and small friction resistance of high efficiency. As shown, clockwise and counterclockwise output torque is linear. Under normal operating conditions, the recommended safe coefficient of the double-acting actuators - % single-acting actuator single-acting actuator selection of SR series pneumatic actuators, for example in the application of the reset spring, the output torque is in the process of two different operating income, according to the schedule position, each operation producing two different torque values. Spring return actuators of output torque by force ( Air pressure or spring) On the first lever income status: the output torque is made up of air pressure into the lumen after compression spring, known as' air travel output torque in this case, the air pressure to the piston from degrees to position, due to the spring compression reaction force, torque from the start when the maximum taper gradually to the second condition: cavity of the output torque is loss of gas spring back the force on the piston, known as' spring travel output torque in this case, because the spring elongation, output torque from diminishing straight degrees such as described above, single-acting actuator is based on the two conditions to create a balanced torque on the basis of the design. As shown. In each case, by changing the number of spring and air pressure on each side of the relationship ( As the root spring and per side. The gas source, or vice versa) , it is possible to obtain unbalanced moment in spring return applications can obtain two conditions: the loss of gas open or closed. Under normal working conditions, the recommended safe coefficient of the spring return actuators - % click to see more of pneumatic actuators
