ME series pneumatic actuators

Introduction and application

The ME series pneumatic actuator adopts the shifting fork structure. Compared with the rack and pinion structure actuator of the same cylinder size, the output torque is larger. In addition, the shifting fork structuraction transmits the torque curve generated by the actuator output, and more matches the torque curve of angle stroke rotary valve, such as ball valve and butterfly valve. It is widely used in the production process of petroleum, chemical, metallurgical, pharmaceutical, electric power and other industries.

Technical Parameters

▲Output moment: single action 5~46979N.m
                               Dual effect 11~106910N.m
▲Air source pressure range: 3bar~8bar
▲Ambient temperature: -20°C~+80°C (standard)
                                       -40°C~+160°C (special)
▲Top flange standard: ISO5211/DIN3337

Product features

▲Air source interface meets VDI/VDE3845 NAMUR standard;
▲Independent stroke adjustment, precise full-close and full-close position adjustment, adjustable angle ±10°;
▲The top mounting hole complies with VDI/VDE3845, and can be  used to install accessories such as positioners and limit switches;
▲The upper and lower metal self-lubricating bearings of the output shaft are embedded on the cylinder block. This kind of rigid support design is different from the engineering plastic bearing structure of other actuators, which protects the  output shaft to the maximum extent and keeps it in a vertical state. It will not tilt under the influence of external forces, causing eccentric wear of the sealing ring and reducing the service life;
▲The single acting actuator adopts the compound structure of silentspring, which completely avoids the deformation of spring and makes the life of spring longer and more reliable;
▲Test with load: no leakage more than 1300000 times.
