  • GEMU 658, 688 Diaphragm Valve, Metal

    Construction
    The GEMU 658/688 2/2 way or multi-port metal diaphragm valve has a two stage actuator.
    The actuator has a stainless steel housing and is controlled by two pistons working independently of each other

    Features

    • Suitable for inert, corrosive, liquid and gaseous media
    • Chemical resistance of actuator
    • CIP / SIP cleaning and sterilizing capabilities
    • An adjusting screw in the actuator head enables the setting of the opening and closing function and also the setting of a part stroke (for reduced flow)
    • Quick ON/OFF operation and the possibility for precision dosing of the working medium
    • Insensitive to particulate media
    • Valve body and diaphragm available in various materials and designs
    • Various connections available
    • Compact design
    Advantages
    • Optional flow direction, will seal in either flow direction up to full working pressure
    • Optional mounting position
    • Can be individually used. Space consuming piping systems and valve wiring are no longer necessary
    • Extensive range of accessories (e.g. pilot valves, limit switches, field bus connections)
