◆ Pneumatic actuators are a category of actuators. Pneumatic actuators can also be divided into two types: single-acting and double-acting: the switching actions of the actuators are all driven and executed by the air source, which is called DOUBLE ACTING. SPRING RETURN (single-acting) switching action is only the opening action is pneumatic drive, and the spring return during the closing action. Pneumatic actuators can simply realize fast linear circulation movement, simple structure, convenient maintenance, and can be used in various harsh working environments, such as explosion-proof requirements, dusty or humid conditions.

Design Feature+

◆ Receive continuous air signal and output linear displacement (after power-on/air conversion device, continuous electrical signal can also be received), and some can output angular displacement with rocker arm.

Pneumatic actuators

◆ There are positive and negative functions.

◆ The moving speed is high, but the speed will slow down when the load increases.

◆ The output force is related to the operating pressure.

◆ High reliability, but the valve cannot be maintained after the air supply is interrupted (it can be maintained after adding a retaining valve).

◆ It is inconvenient to realize segment control and program control.

◆ Simple maintenance and good adaptability to the environment.

◆ Higher output power.

◆ With explosion-proof function.

◆ Compact dual-piston gears, rack-and-pinion structure, precise meshing, high efficiency, and constant output torque.

◆ The aluminum cylinder, piston and end cover are the lightest in weight compared with the actuator of the same specification structure.

◆ The cylinder body is made of extruded aluminum alloy and has been treated with hard anodizing. The inner surface has a hard texture, high strength and hardness. The sliding bearing made of low-friction materials avoids direct contact between metals, has low friction coefficient, flexible rotation and long service life.

◆ The installation and connection dimensions of pneumatic actuators and valves are designed according to international standards ISO5211, DIN3337 and VDI/VDE3845, and can be interchanged with ordinary pneumatic actuators.

◆ The air source hole complies with NAMUR standard.

◆ The shaft assembly hole at the bottom of the pneumatic actuator (in line with ISO5211 standard) is a double square, which is convenient for linear or 45° angle installation of the valve with a square rod.

◆ The top and top holes of the output shaft comply with NAMUR standards.

◆ The adjustment screws at both ends can adjust the opening angle of the valve.

◆ The same specifications are double-acting and single-acting (spring return).

◆ The direction can be selected according to the needs of the valve, clockwise or counterclockwise.

Install solenoid valve, positioner (opening indication), echo device, various limit switches and manual operation devices according to user needs.
