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.
