This Danfoss WVX / WVF15-style 1/2 inch pressostatic water valve is used in compatible FMB / Firbimatic, Union, and Realstar dry cleaning machine refrigeration and water-control systems.
The valve helps regulate condenser water flow in response to refrigeration pressure so the machine can maintain proper cooling, recovery performance, and stable refrigeration operation.
Use this listing when the original machine part number, valve size, body markings, pressure-control arrangement, fittings, and service manual match 0913002 / F6528.

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.
