Honeywell RP971A1007 Pneumatic Ratio Relay:

A four port nonbleed pneumatic relay which produces a modulating pressure output, proportional in a fixed ratio to pilot input changes.

It is used to control pneumatic valve or damper actuators in sequence from a single thermostat.
Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.
