Stop valves with bellows seal ARI-FABA®-Plus
Designed for use as a shut-off valve in industrial piping systems. Bellows stem seal valve completely isolates the stem and stuffing box slave node from the eyes of the environment. This is especially important for use in high temperature (steam, thermal oil), explosive and toxic environments.
Since 2009, the company ARI releases a new version of bellows valves ARI-FABA®-PLUS, which is concentrated forty years of experience the production of these valves company ARI.
