EBM PAPST cable for NRV valve 27458.36119

This cable, SKU 27458.36119 from EBM PAPST, connects the NRV valve in fans and combustion control systems. It ensures stable signal and power transmission between the valve and the burner control or fan system. The cable is made of materials resistant to temperature loads, vibrations, and long-term operation in boiler conditions. It is intended for use with EBM PAPST NRV series fans with control valves, modulating premix burners, and boiler systems with NRV valve control.

When replacing a cable of this type, the connector style, pin configuration, and wire length must match the original. Cables for valves are selected by the number of conductors, their cross-section, and the type of connectors at each end. The cable must withstand the ambient temperature inside the burner enclosure and be routed away from hot surfaces and moving parts. Compare the new cable's connector shape and pinout with the existing one before installation.

A faulty cable typically causes the burner control to display a fault code or the valve to fail to open or modulate correctly. Loss of signal or unstable contact may prevent the fan and gas valve from responding together, disrupting the air-fuel ratio in modulating burners. Check for loose connectors, visible damage to the sheathing, or continuity loss at the valve terminals using a multimeter to confirm a cable fault before replacement.
