The series 61 Booster Relays reproduce pneumatic signals in a 1:1 ratio for applications where input isolation or increased flow capacity are required.

61H is a High-Capacity Booster Relay designed to improve the stroking speed of large diaphragm valves.

61VH is a High-Capacity Booster Relay designed for use on control valve actuators that require very fast stroking speeds. Both 61H and 61VH feature a stabilizing bypass needle valve between the input and output, which eliminates the need for an externally piped bypass.
