Honeywell RP470B1001 Pneumatic Selector Relay

The Honeywell RP470B1001 Pneumatic Selector Relay is an essential part in HVAC systems for it regulates the supply of compressed air to control the pneumatic actuators and dampers. This relay works in a way that compressed air is used to move a spool within the internal structure of the relay. This spool movement redirects the airflow to other output ports meaning that it can switch between different control signals. Such a level of control is essential for achieving the Bettercomfort of the building, energy consumption, and the performance of the system. It can accept numerous control signals and control numerous pneumatic parts due to its flexibility.
