Rexroth Actuator Positioners are compact, pneumatically operated devices used for accurate positioning of engine governor control arms, butterfly valves, carburetors and other low-force mechanisms.
Rexroth offers three types of positioners: diaphragm with radial motion lever, diaphragm-linear, and cylinder-linear. All three models use the same basic principle of applying a predetermined air pressure (supplied by a Rexroth Type "H" Controlair® Valve or Type M PLUS™ proportional pressure control valve) to act on a diaphragm or piston to compress a positioning spring. The actuator lever then assumes a specific position which corresponds to the applied pressure and to the control valve handle position.
Our Actuator Positioners feature light-weight, strong, die-cast construction with a minimum of connections. Years of performance in heavy construction vehicles, drill rigs, marine applications, and other types of installations have proven them to be rugged and highly dependable.
AB-1 Basic AB Type Two-Direction Positioner is made from the basic AA Type and the addition of a separately controlled stop cylinder.
