Description
The Crandall 2353-501-CSS Pneumodular Diverting Relay 3–20 PSI is a pneumatic switching device used in HVAC control and pneumatic logic systems to divert control air based on defined pressure thresholds. This relay reacts to increasing pneumatic pressure and switches a single-pole changeover contact to route air or control signals to alternate paths. Built to Crandall specifications, it delivers dependable actuation across a 3–20 PSI range for stable control logic operation. Ideal for HVAC technicians and controls contractors, it helps manage pressure-based control sequences in air handling and pneumatic control loops with repeatable performance.
