Cylinder stays in position.

Press Release Summary:

Model RA/8000 servo-controlled cylinder provides exact positioning of piston through electrical or pneumatic control signal as to be held in any desired position, even under changing load conditions. Positioning feedback mechanism included with cylinder links controller to piston rod. Cylinder is available in 63 to 320 mm dia, with stroke lengths from 100 to 600 mm, and electro-pneumatic (4 to 20mA) or pneumatic (0.2 to 1.0 bar) positioners.

Original Press Release:

Servo controlled cylinder offers highly accurate positioning

Norgren, world leader in pneumatic components and automation systems, has expanded the popular RA/8000 cylinder range with the launch of a servo-controlled cylinder.

Unlike ordinary cylinders, the servo-controlled model offers exact positioning of the piston through an electrical or pneumatic control signal, ensuring that it will be accurately held in any desired position, even under changing load conditions.

Applications for the highly versatile cylinder include open and closed loop process control systems in a number of demanding industrial areas, such as temperature control or pressure regulation in power stations, chemical plants, gas works, food processing, steel works and paper mills. Suitable for use in harsh environments, it is vibration resistant, dust proof and splash proof.

A positioning feedback mechanism included with the cylinder links the controller to the piston rod. Coupled with the position controller, this system allows higher thrust and shorter positioning time than ordinary cylinders.

Comprising of a Foxboro/Eckardt (model numbers RA/8000/P1 to P4) or Siemens (model numbers RA/8000/P5 to P8) universal position controller, Norgren's servo cylinder features left or right hand versions, which can be direct or reverse acting.

The RA/8000 is available in a wide variety of diameters, from 63 to a large 320mm. Stroke lengths are from 100 to 600mm, while the positioners are offered in electro-pneumatic (4 to 20mA) or pneumatic (0.2 to 1.0bar) versions. In addition, a wide range of mounting options are available to suit various applications.

Featuring high performance, stability and reliability, the RA/8000 conforms to IS06431, VDMA24562 and NFE49-003-1.
