This page explains how Corbett Equipment handles fitment questions, support requests, and order communications.

How vacuum leaks, worn seals, pump condition, and motor fitment affect distillation performance on FMB, Firbimatic, Union, and Realstar dry cleaning machines.

A practical method for matching dry cleaning machine replacement parts across FMB/Firbimatic, Union, and Realstar model families.

Machine parts supported by one or more manuals, factory price lists, invoices, model-lineage records, ETL references, or verified Corbett Equipment service sources.

Corbett Equipment explains its preliminary damages model, why the estimated economic harm already exceeds $200 million, and why that figure does not yet include royalties, counterfeit parts, copyright damages, trademark damages, platform liability, or additional market-suppression losses.

Why service teams should confirm part fitment against manuals, photos, model lineage, and machine-specific information before ordering.

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. Technical Specifications Component type: 1/2 inch pressostatic / pressure-operated water regulating valve. Valve family: Danfoss WVX / WVF15 / WVi5-style 1/2 inch water valve, with older FMB/FM manual references to WYF15 D.1/2. Primary application: refrigeration condenser water-control service on compatible FMB / Firbimatic, Union, and Realstar dry cleaning machines. Function: regulates condenser water flow in response to refrigeration pressure to support cooling, recovery performance, and stable refrigeration operation. Nominal size: 1/2 inch. Verify the installed valve body, fittings, pressure-control arrangement, and machine service manual before ordering. Confirmed price-list description: 1/2 inch Danfoss WVX Water Valve / Water Valve Refrigeration. Companion 3/4 inch pressostatic valve: 0913003 / F13623. Do not substitute the 3/4 inch valve for this 1/2 inch listing unless the machine manual and installed component confirm it. Nearby thermostatic valve references 0914002 / V13841 and 0914004 / V1566 are different components and are not substitutes for this listing. Part Numbers & Cross References Use this section to separate direct brand part numbers from cross-reference and legacy/manual references. Always verify the installed component, valve size, body markings, fittings, pressure-control arrangement, and service manual before ordering. Part Numbers FMB / Firbimatic 0913002 09.13.002 F6528 F8526 Union 0913002 09.13.002 Realstar 0913002 Cross References FMB / Firbimatic Legacy price-list cross-reference: F6528, described as a 1/2 inch Danfoss WVX Water Valve / Water Valve Refrigeration. Manual-page legacy reference: F8526 appears in older FMB/FM valve-table material for pressostatica tipo WYF15 D.1/2. Confirm against the installed component and manual before substitution. Valve-family wording found in manuals: Danfoss WVX, WVF15, WVi5, and WYF15-style 1/2 inch pressostatic water valve references. Union FMB / Firbimatic cross-reference: 0913002. Formatted manual-style reference: 09.13.002. Legacy FMB / Firbimatic references for verification: F6528 and F8526 when the Union machine manual, installed valve, and valve size match. Realstar FMB / Firbimatic cross-reference: 0913002. Legacy FMB / Firbimatic references for verification: F6528 and F8526 when the Realstar machine manual, installed valve, and valve size match. 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.

Sovrana and other derivative references Sovrana and other derivative-model references may appear in Corbett lineage records. Treat them as research clues only unless the installed component, machine manual, and part-number path confirm the application. 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.
