Description
The Crandall 2372-501-CSS Low Pressure Selector/Volume Booster Relay is a pneumatic control relay designed to compare and divert the lower of two pneumatic pressure signals while boosting output volume for reliable downstream control. This relay improves low-pressure signal strength and stability, helping pneumatic actuators and other devices respond more consistently. Built to Crandall specifications, it supports stable pneumatic logic behavior in HVAC and building automation systems. Ideal for HVAC technicians and controls contractors, it helps maintain accurate control air distribution and dependable system performance.
