  • GEMU 600 HP High Purity Diaphragm Valve, Plastic

    GEMU 600 HP High Purity Diaphragm Valve, Plastic

    Construction
    The GEMU 600 HP 2/2 way valve has a low maintenance piston actuator which can be controlled by inert gases. It has a stroke limiter, a manual override and an integral optical position indicator as standard.
    Normally Closed, Normally Open and Double Acting control functions are available.

    Features

    • Suitable for inert and corrosive liquid and gaseous high purity media
    • All medium wetted parts and the housing are made of high quality plastic materials
      • Valve body: PFA-lnliner/PVDF-Outliner (carbon-filled)
      • Diaphragm material: PTFE/EPDM
      • Actuator PP glass fiber reinforced
    • Control connection in flow direction as standard, therefore installation in restricted spaces possible
    • Manufactured under cleanroom conditions
    Advantages
    • Good Kv value
    • Contamination level according to SEMI spec. F 57
    • Minimal deadleg
    • Optional flow direction, will seal in either flow direction up to full working pressure
    • Due to its design particularly suitable for polishing agents and slurries
    • Optional mounting position
    • Optional accessories
      • Electrical position indicator with microswitches or proximity switches
      • Pneumatic or electro-pneumatic positioners
      • Control air adapter for pilot valves according to Namur

  • GEMU 677 HPW High Purity Diaphragm Valve, Plastic

    • Assembled, tested and packaged under class 100 cleanroom conditions
    Advantages
    • Good Kv / Cv value
    • Minimal deadleg
    • Optional flow direction, will seal in either flow direction up to full working pressure
    • Due to its design (diaphragm valve, i.e. soft flow deviation) also particularly suitable for polishing agents and slurries
    • Optional mounting position
    • Optional accessories
      • Electrical position indicator
      • Locking device
