Honeywell Pneumatic Selector Relay, used in lockout, repeater and lower of two input pressure applications

Three-port relays used in HVAC systems to perform a variety of relay functions; transmit the higher of two input signals, lock out one pressure signal when a second signal is higher, or transmit the lower of two pressure signals. Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices. Features Uses diaphragm-logic technology. In-line, wall, or panel mounted. Sharp-barb air connections. Molded plastic construction.
