Ventilating Valve Type 595 PVDF

  Datasheet (PDF)

The Georg Fischer SYGEF Standard Ventilating Valve Type 595 PVDF is a high-integrity process control component engineered for dependable vacuum relief, line venting, and controlled aeration across aggressive chemical handling and high-purity fluid applications. Manufactured from premium polyvinylidene fluoride (PVDF), the valve body houses an internal spring mechanism coated with HALAR (ECTFE) to provide outstanding resistance against aggressive acids, solvents, and oxidizing media while facilitating sensitive, rapid-response actuation.Engineered for demanding industrial environments, this ventilating valve prevents vacuum-induced pipe collapse during drainage, optimizes system fluid dynamics, and supports critical service in semiconductor manufacturing, chemical distribution networks, and pharmaceutical-grade purified water (PW) and deionized water (DI) installations.
