Model 610F booster relay
Model610F is similar to 61F. It is typically used in measurement circuits where a higher degree of accuracy of the 1:1 transmission is required. This model have preformed diaphragm for maximum accuracy and sensitivity. The 610F has an external zero adjustment for correction of an offset between the input and output pressures.

Series 61 booster relay
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.

Model 61VH
Model 61VH is a high-capacity volume booster designed for use on control valve actuators that require very fast stroking speed. In addition, it can respond to small or gradual input changes without jeopardizing steady-state accuracy or stability. It is particularly well suited to double-acting, large-volume actuators.
