Features • All wetted parts made of PFA or PTFE • High flow rate with low-stress media channelling • Optional flow direction • Ideally suited for corrosive media • Metal-free design • Optional version with ECTFE union nut • Also available as T valve • Clean room production, fulfils SEMI F57 The ultra pure 2/2-way diaphragm valve GEMU C67 HPW CleanStar is manually operated. 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. A seal adjuster (not with AG 4) and an optical position indicator are integrated as standard. 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. • Body configurations: 2/2-way bodies l T body l V valve body • Connection types: Flare l Flare SpaceSaver l Nexus Connect® l Nexus Connect® SpaceSaver l PrimeLock® l PrimeLock® SpaceSaver l Spigot l Super 300 Type Pillar® SpaceSaver l Union end l Welded-on Nexus Connect® • Body materials: PFA l PP-R, natural l PVDF • Diaphragm materials: PTFE/EPDM • Conformities: EAC l FDA l TA Luft (German Clean Air Act) Technical data depends on the respective configuration

Product description

Designs Body configurations Body configuration T valve body (code T) The T body has 3 connections. The opposing connections (X and Z) are classed as main pipe, as media flows between them at all times, regardless of the position (open/closed) of the actuator. The branch (Y) is located at a 90° angle to the main pipe. The flow across this connection can be influenced via the actuator. The 2/2-way body is the most commonly used body configuration. Thanks to the seal created by the weir-style body, the flow direction is freely selectable. Various pipe and tube connections can be connected to the...

Designs Special versions Description High Flow (code F) In actuator sizes 2 and 3, the 2/2-way body is also available in a so-called High Flow design. This body version has a flow-optimized weir geometry. This reduces the pressure loss and thereby facilitates a higher flow. High Flow valve bodies are often used when higher volume flows are required. The upper image shows a cross-section of a standard version without High Flow. The lower image shows a cross-section of a High Flow design (code F). ECTFE union nut (code E) The central union nut, which connects the actuator to the body via a thread,...

Valve body material: PFA (code 30), actuator sizes 1, 2 and 3 Valve body material: PFA (code 30), actuator sizes 4, 4E * Note: The temperature/pressure diagram is only an aid. The data refers to water as a working medium. A change of operating conditions or other media may result in deviations. In case of doubt, it is advisable to test the behaviour of the material under the definitive operating conditions in a test installation. Temperatures below 0 °C can have a negative influence on the actuation speed. The pressure-bearing valve bodies are designed to maintain their functionality unchanged...
