Pneumatic Selector Relay, transmits higher of two input pressures
Overview
Three-port relays are used in HVAC systems, to perform a variety of relay functions, such as; 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.
Features
- Uses diaphragm-logic technology.
- In-line, wall, or panel mounted.
- Sharp-barb air connections.
- Molded plastic construction.
