Related Parts To Verify Separately
0913003 / F13623 is the companion 3/4 inch pressostatic valve.
0914002 / V13841 and 0914004 / V1566 are thermostatic valve references, not this 1/2 inch pressostatic water valve.
Machine Fitment
Machine fitment for Water Valve, Danfoss 1/2 in | FMB / Union / Realstar 0913002 is organized through Corbett Equipment master manufacturer and model-lineage evidence. Use this section as a fitment-reference map, then verify the installed component, machine data plate, service manual, dimensions, voltage or pressure ratings where applicable, mounting, fittings, and part-number path before ordering.
Master manufacturer / model lineage
Corbett Equipment and FXT Factory records treat FMB / Firbimatic as the master machine-model lineage for this catalog family. Union, Realstar, and Sovrana references are derivative-reference families that must be matched through the installed component, manual table, and machine-specific service record.

Ordering Verification
Confirm the part number, installed valve markings, valve size, fitting style, pressure-control arrangement, and machine model before ordering.
Confirm this is the 1/2 inch pressostatic water valve before replacing it. The nearby 3/4 inch pressostatic valve and thermostatic water valves are different parts.
For FMB / Firbimatic, Union, and Realstar machines, match the listing against the machine data plate, service manual table, installed component markings, and physical valve/fitting configuration.
Contact Corbett Equipment if you need help matching the valve to a FMB / Firbimatic, Union, Realstar, or related FMB-lineage dry cleaning machine.
