The ultra pure 2/2-way diaphragm valve GEMÜ C60 CleanStar® has a plastic piston actuator and is pneumatically operated. A stroke limiter (not with AG 4) and an optical position indicator are integrated as standard. All media wetted parts are produced from PFA or PTFE (HPW version). For the HPS version, there is a choice of valve bodies made of PP-R, natural or PVDF. This High Purity version of the CleanStar® series complies with the strictest purity standards and boasts high chemical resistance. It can also be used with high media temperatures. As such, it is often used at the supply and distribution level in semiconductor factories.
