maintaining system integrity by de-energizing the gas valve if venting becomes obstructed or the blower fails

which requires a complete furnace rollout switch replacement once triggered

The unit features a 5/8" x 3/4" orifice and a black adjustment spring calibrated for a 6–9" water column (W

and EV250B valve series

The durable construction helps prevent signal loss and mechanical failure in high-vibration environments

KMC Controls XEC-3004 Transducer 320788-702 maintaining system integrity by de-energizingThe KMC Controls XEC 3004 is a professional grade E I P transducer engineered for precision in building automation and HVAC pneumatic control. This high performance interface converts analog voltage (E) or current (I) signals into a proportional 3 15 psi linear pneumatic (P) output, essential for the accurate positioning of damper and valve actuators. Designed for maximum field flexibility, it accepts multiple input ranges including 1 5 VDC, 2 10 VDC,
