COOL-FIT 2.0 Butterfly valve kit type 567

  Datasheet (PDF)

The Georg Fischer COOL-FIT 2.0 type 567 PVC-U bare shaft butterfly valve kit is engineered for reliable flow isolation and modulation within pre-insulated secondary cooling and chilled water distribution systems. Configured with a bare shaft drive stem, the valve features a standardized F07 mounting flange interface conforming to DIN/ISO 5211, providing versatile compatibility for direct mounting of quarter-turn pneumatic actuators, electric actuators, or manual operating gearboxes without complex modifications. Constructed with a high-integrity PVC-U valve body and disc matched with resilient EPDM elastomer seals, the unit ensures dependable bubble-tight shut-off under continuous nominal system pressures up to 10 bar. To provide complete piping and thermal continuity, the kit is delivered as an all-in-one installation solution comprising pre-insulated PE100 SDR11 spigot flange adaptors, glass-fiber reinforced polypropylene backing flanges with internal steel inserts (PP-Steel), precision fastening bolts, and rigid, vapor-tight insulation half shells. The PE100 SDR11 metric spigot ends enable swift and secure jointing via electrofusion couplers directly into the COOL-FIT 2.0 piping network. Tailored specifically for refrigeration, industrial process cooling, data centers, and commercial air conditioning loops operating from 0 degrees to +60 degrees Celsius, this corrosion-free thermoplastic assembly eliminates cold bridges, prevents moisture condensation, and maximizes energy efficiency over a long, maintenance-free service lifespan.
