The Booster Relay (model BR) is designed to meet conventional speed control applications. It produces a volume boosting action and contains an integral stabilizing by-pass valve, adjusted by a screwdriver turning the adjustment screw in the body. By opening this valve, it is possible to improve the stability of the positioner – volume booster – actuator circuit.
BR is specifically designed to be piloted by digital-pneumatic valve controller (such as our FasTrak Compact Positioner).
