Features & Benefits

ON-LINE ADAPTIVE CONTROL: During operation, the unit continually optimizes control behaviors and travel times in response to changes in line media pressure

DIAGNOSTICS: Bray’s Series 6A positioners feature corrective and preventative maintenance self-diagnostic checks. All diagnostics run constantly, may be continually monitored, and recorded

AIR SUPPLY MONITOR: An additional feature of the Series 6A is an internal monitor that transmits a fault signal alarm if the air supply fails. The alarm is shown locally on the LCD and may be sent to the remote control panel

LOCAL POSITION ADJUSTMENT: Valve position can be manually adjusted locally by removing the housing cover, then using the push buttons to override the remote command signal

FLOW RESTRICTORS: Precise control of even the smallest pneumatic actuators through internal Flow Restrictors

POSITION INDICATOR: In addition to the LCD display, valve position is clearly shown over a distance by a yellow indicator

LOCKING DEVICE: For high vibration applications, the Series 6A features, as standard, a friction clutch locking device
