Ventilating and Bleed Valves ABS Georg Fischer

ABS ventilating and bleed valves (Type 591 and Type 595) provide automatic aeration and deaeration for industrial plastic piping networks. Installed at high points in piping runs, they reliably exhaust trapped air during charging, vent accumulated gases during operation, and admit air to eliminate vacuum collapse risks during system drainage. Engineered by Georg Fischer from durable ABS resin with chemically resistant EPDM or FKM seals, these valves integrate directly into solvent cement piping networks across chilled water circuits, industrial cooling loops, water treatment lines, and marine installations.
