Item # R431009018, Rexroth BA1 Radial Motion Type Positioner


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.

BA-1
Basic AA Type, Single Direction Positioner with a "vernier" feature added by the use of an additional diaphragm that is controlled separately. (An H-4 Controlair® Valve is a great combination.) This allows for exact positioning and very fine control.
