ARI Armaturen ARI-FABA® Plus
Maintenance-free double metal bellows stop valve for isolation on industrial steam and hot-fluid lines.
ARI-FABA® Plus is the bellows stop valve of ARI-Armaturen: stem sealing is done by a double metal bellows, so there is no gland to maintain, and shut-off is metal to metal. The series covers DN 15–400 in the metric line (PN 16–40) and 1/2"–10" in the ANSI line (classes 150–300), with working temperatures of up to 200 °C with PTFE-carbon gasket and up to 250 °C in the version with pneumatic actuation.
From this series we can quote new valves to order, by type code (35046, 22046, 23046, 34046 and their variants), through supply channels in the European Union. For a correct quotation the customer sends the DN, PN, body material, connection type (flanges or welding) and the fluid with its working temperature.
