    GEMÜ CleanStar® C60 (Air Operated) and C67 (Manual) products are used for chemical handling in the following applications:

    • Etching and coating processes

    • Chemical purification

    • Manufacture and filling of chemicals

    • Chemicals for water and waste water treatment

    The purity of the process media used in many high-tech areas is increasingly decisive for the quality and quantity of the products. The GEMÜ C60 and C67 product range of use is broad and includes sectors such as optics, aeronautics and astronautics or medicine via the pharmaceutical industry, biotechnology and gene technology.  Additionally, this product’s range of use covers precision mechanics and micromechanics, electronics and microelectronics or semiconductor production (including flat screen technology), photovoltaic systems and light emitting diodes. Numerous plant designers and end users select GEMÜ products when equipping their devices and production plants for media control and regulation, as well as process equipment for cleaning, coating, etching, and filling. GEMÜ offers an extensive range of products which are suitable for these applications due to their high resistance and uncompromising purity.

    GEMÜ’s High-Flow valve body (weir design) provides:

    • Significantly improved flow rate due to flow-efficient seat contour

    • Low pressure loss resulting in cost savings

    • Low-impact media handling due to gentle flow lines

    • Longlife seat contour

    • Up to 100 % Kv/Cv value increase *(depending on nominal size/connection)

    • Same outer dimensions and connection to actuator as standard body

  • GEMÜ offers customers multi-port valve block solutions made of high performance thermoplastic materials such as PTFE or PVDF for wet processes in the semiconductor industry and solar cell production industry that include controlling cleaning media and chemicals.

    Thanks to the custom design applied to each multi-port valve block, a variety of functions are united in the smallest of spaces. These functions include:

    mixing

    dividing

    diverting

    draining

    feeding

    Multi-port valves can also fulfill safety functions, double shut-off (double block and bleed), cross connections and control functions. These functions can serve very specific purposes in a variety of installations such as the taking of samples, the distribution of chemicals, the distribution of cleaning media and ensuring a minimum flow rate. There are also numerous more complex functions in connection with process automation. Pressure or temperature sensors can be integrated for example. Intelligently designed, multi-port valve blocks can be developed into compact system components with a high degree of functionality.

    Lightweight, compact, quick to install and multipurpose – these requirements are becoming increasingly important for system components. Complex control of liquid is generally carried out by multiple individual valves. The individual valves are connected to one another by a similar number of fittings and piping . This requires a large amount of space and assembly is time-consuming because of the higher number of individual parts. Every assembly point and pipe connection has the potential for leaks, which increases the safety risk. GEMÜ compact plastic multi-port valve blocks are the ideal components to reduce these safety risks. The multi-port valve blocks are manufactured from a single block of material and can be designed to perform multiple functions as lightweight and compact units that save space.

  • Construction
    The GEMU C30 Hydra-Gauge is equipped with a PFA transmitter and a pressure gauge. The body is made from PFA and can be directly integrated into the pipe system by commom flare unions. A PFA double diaphragm prevents contamination of the working medium. Only the PFA body and the PFA diaphragm are wetted parts. The pressure is transmitted by a monitor liquid (50 % Dl water and 50% IPA (isopropyl alcohol)). The pressure gauge complies with EN 837-1.

    Features
    • C30 is especially suitable for pressure measurement of ultra high purity chemicals
    • All wetted parts are made from High Purity PFA
    • Pressure transmission by double diaphragm technology
    • Pressure gauge can be rotated through 360°
    • Not suitable for applications with strong vibrations, pulsing process pressure or pressure peaks; provide for suitable pulsation dampers and throttling sections, if necessary
    Advantages
    • Minimal deadleg
    • The proven GEMU CleanStar® technology is the basis of the transmitter
    • Working medium hermetically isolated from the gauge by a double diaphragm
    • Proven long term reliability
    • Pressure gauge can be positioned through 360° enabling individual user options
  • GEMU C67 HPW Clean Star 2/2 Way Diaphragm Valves
    The CleanStar® C67 HPW manually operated ultra pure 2/2 way diaphragm valve has a complete PFA-HP body. All medium wetted parts are made of PFA-HP or PTFE (diaphragm)...

  • Construction
    The CleanStar® C67 HPW manually operated ultra pure 2/2 way diaphragm valve has a complete PFA-HP body. All medium wetted parts are made of PFA-HP or PTFE (diaphragm). The exterior bonnet parts are made of PVDF. Standard features are (1) Stroke limiter for minimum flow regulation. (2) Integral mounting lugs. (3) Leak sensor connection. (4) Union nuts in PVDF-HP or PFA-HP. (5) Optical position indicator.

    Features
    • Specifically designed for high purity media
    • Metal free
    • High flow capability
    • Union nuts / flare connections compatible with industry standards
    • Manufactured under clean-room conditions
    Advantages
