The four port, snap acting relay converts a proportional air pressure change from a controller to a positive (two-position) pressure change. It can also divert a supply line to one of two branches. Replacement device is available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.

• Manually adjustable switching pressure.
• Sharp barb connections for 5/32 inch (4 mm) O.D. plastic tubing.
