GEMÜ C67

The GEMÜ C67 CleanStar 2/2-way manual diaphragm valve provides metal free flow isolation for high purity semiconductor and critical chemical manufacturing applications. The GEMÜ C67 accommodates nominal sizes from DN 4 to DN 25, regulates upstream operating pressures up to 6 bar, and features a complete PFA-HP body with a PTFE diaphragm. Key Performance Capabilities: Ultra Pure Media Security: The GEMÜ C67 CleanStar uses a complete PFA-HP body and PTFE diaphragm manufactured under strict SEMI F57 cleanroom conditions, preventing particulate contamination to guarantee yield integrity within high purity semiconductor supply lines. Mechanical Flow Regulation: The GEMÜ C67 CleanStar integrates a standard seal adjuster and an optical position indicator, enabling plant engineers to secure minimum flow regulation and drastically reduce diagnostic downtime during manual pipeline interventions. Environmental Resilience: The GEMÜ C67 CleanStar incorporates PVDF exterior bonnet parts and an optional ECTFE union nut, securing the internal valve mechanism against aggressive external atmospheres to lower long-term replacement costs in corrosive processing zones. Safety & Compliance: Leakage Detection Capability: The GEMÜ C67 CleanStar features an integral leakage sensor connection, allowing proactive monitoring of the PTFE diaphragm to prevent catastrophic chemical spills and eliminate unplanned hazardous process halts. Note: The maximum operational media temperature and pressure ranges depend strictly on the specific diaphragm material and selected body configuration for the GEMÜ C67 CleanStar.
