Overview :

Designed to meet high-speed control applications, the Model 61H F/R Booster Relay produces a high volume boosting action. Its primary purpose is for use with valve positioners, although it can be used by itself for the high volume of air it can control. (This relay is not normally used in measuring circuits.)

The relay contains an integral stabilizing bypass valve, eliminating the need for an externally piped bypass. The bypass opening is controlled by a screwdriver adjustment in the body of the relay which permits tuning for optimal dynamic response. Opening this valve improves the stability of the positioner/relay/actuator circuit.
