Pneumatic Actuators All PTM-actuators are based on the rackand pinion principle, picture 2. This fact is responsible for small dimensions. For different mounting alternatives all PTMactuators can be mounted on three or four mounting surfaces. Rotation angles more than 185° are available. Our progressive working end position damping starts working just about 10° before reaching the end position by throttling the exhaust air automatically. This guarantees reaching the exact end position. This excludes bouncing in the end position even during air pressure variation. A technically necessary backlash...

Brief technical data aluminum hard or black anodized steel parts of stainless material or corrosion resistant short time gas nitration Operation / mounting position: Operating temperature: Operating media: filtered oiled or filtered oil-free air Attention: Only oil-free air should be used at low rotation speed to guarantee smooth movement. all PTM Pneumatic Actuators are maintenance-free. Operating pressure: maximum 8 bar = 118 psi (specs are based on 6 bar = 88 psi) Rotation angle: rotation angle max. 365°, 185° and 95° adjustable until -20° in total by adjustment screws if possible use keyway/key,...

Three Position Torque Cylinder Keyword : Mid position Actuators with an exactly defined mid position (Attention: Backlash !) are based on three piston units. The two external pistons push the piston with the rack into the mid position. If the two cylinders on both sides are without pressure and only the center piston is pressurized, the pinion will turn around the complete angle. The speciality of this construction is, that in spite of the small construction all pistons have end position damping. Field tests did prove, that this pneumatic end position damping is superior to the normally used...
