Coleman-Sanborn TA5590856 Pilot Unloader Valve

The Coleman-Sanborn TA5590856 Pilot Unloader Valve is a model-specific Coleman-Sanborn component, carrying the 070-0057 designation and the associated part numbers TA5590856 and TA5090412, which helps technicians identify and source the exact part in manuals and catalogs for Coleman-Sanborn equipment. As a pilot unloader valve, it is designed to interface with the pilot circuit in compatible assemblies and to be installed where these identifiers are specified in service documentation. It is rated for a 95-125 PSI operating range, defining the pressure window the valve is designed to withstand and making it essential to verify compatibility with the rest of the system before ordering. Having all three identifiers—070-0057, TA5590856, and TA5090412—on hand assists accurate cross-referencing with manuals and catalogs, helping ensure the correct unit is sourced and installed. The clarity of identification with 070-0057, TA5590856, and TA5090412 alongside the PSI rating can help technicians confirm compatibility and source the correct valve for repairs.
