This Rovel 1/2 inch normally closed air-operated valve, part 0901083, is used as a pneumatic and fluid-control valve on compatible FMB / Firbimatic, Union, and Realstar dry cleaning machines.
The valve is a single-acting normally closed gate-style valve. In the rest position the valve remains closed; when actuated by air pressure it opens to allow the machine circuit to flow.
The product label identifies the component as VALVOLA VATAL 130 1/2", Cod. 1616, Comm. n° 255999, Made in Italy. Use this listing when the installed valve, machine manual, and service records match FMB / Firbimatic 0901083, Union PU0901083, or Realstar 0901083.

Machine Fitment
Machine fitment for 1/2 in NC Air Operated Valve | FMB 0901083 / Union PU0901083 / Realstar 0901083 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.
