Check Valves PVC-C Type 561 and 562

This category includes Georg Fischer PVC-C check valves, covering Type 561 cone non-return valves and Type 562 spring-loaded check valves. Designed for industrial pressure pipelines, these valves prevent reverse flow while ensuring low pressure loss and dependable sealing in aggressive liquid media. Manufactured from post-chlorinated polyvinyl chloride (RAL 7038) with EPDM or FKM seals and optional corrosion-resistant springs, these valves operate reliably at temperatures up to 80°C. They are suited for chemical dosing, industrial water treatment, and surface finishing lines.
