    High Containment Sampling Valve

    The Andocksysteme ASAM sampling system is a unique method for obtaining powder or liquid samples under very high containment conditions.

    ASAM 1 - "Jar" sample unit for larger sample capture.

    The system works similar to their split valve technology - eg. active and passive valves, however, in lieu of a butterfly valve, the ASAM system uses an active ball-half with a cup machined into the ball-half. When the active valve is closed, it forms a near-flush surface into the process equipment. The sample is captured into a small container, typically glass with a protective steel cage. The container is attached to a passive valve.

    ASAM 2 - Thief sample unit for small sample capture.

    Similar to the design of the ASAM 1 unit except there is no "cup" in the active ball-half to gather powder, instead the active ball-half has a small hole in which a powder thief can be inserted. The hole is made into the "side" of the ball, thus when the active ball-half is closed the hole is hidden away. The thief is held in a plastic tube-bag, which is joined.

    Vacuum Rotary Valve

    The vacuum rotary valve (model VR8V) offers a special "super hygienic" design for metering of your products. We offer both pocket-by-pocket control or simple on-off. Unlike traditional vacuum rotary valves, the Co.Ra valve weighs only a few pounds and assembles without tools!

    Applications:

    • Constant feeding of any process equipment requiring a vacuum seal,
    • Metering of powders into mixing tanks,
    • Any application that needs a rotary valve with positive shut off.

    High Containment DN50 Docking Valve - Passive

     

    For smaller product quantities needing higher containment, Andocksysteme now offers a 2.5” (DN50) split butterfly valve. The success of our production size high containment valve systems lead to the development of a new, miniature version of the ASBV split valve technology.

    The 2.5” size valve was developed for simple, quick and failsafe manual operation, while offering all advantages of our proven large diameter valves. This valve can be integrated anywhere that higher levels of containment are required, and can even be used in sterile areas or for liquids.

    Both the passive and active valves can be fitted to hoses so they do not have to be cleaned before resuming production, resulting in greater time and cost savings.

    The exclusive patented locking system for the 2.5” (DN50) valves makes operation much easier and safer by offering “one-hand docking” of the two valve halves.In fact, the unit is mechanically interlocked in such a way that the valves can not be operated at all unless both valves are properly docked together. More simply, faulty operation is impossible.

    The standard 2.5” split valve is equipped with EPDM white FDA-compliant seals, but can also be equipped with black conductive PTFE when required.With contamination values at 0.01 μg/m3, similar levels of containment are currently unattainable on other systems without the use of vacuum extraction.

     

    PTFE Seals

    A high containment system is only as good as the seals that are used. Ultimately, the sealing materials determine the containment levels achieved.

    The PTFE seals used with our valves offer outstanding thermal and chemical resistance properties, while retaining stringent containment levels. This ensures that the valve is even capable of handling the expansion and contraction of the metal parts during the thermal sterilization (> 121ºC) that aseptic processes typically require.

    Innovative, new PTFE production techniques, combined with an encapsulated elastomer core, ensure that the finished seal will also meet the highest containment requirements in demanding process pressure and vacuum conditions.

    This new manufacturing process results in a seal with a smooth, polished surface, where powder retention is virtually eliminated.

    PFTE Seal Properties:

    • Chemical resistance
    • Broad temperature range (-250ºC to +260ºC)
    • FDA-approved material
    • Very low coefficient of friction
    • No absorption of water

    PTFE Seal Advantages:

    • Cost savings compared to traditional elastomer seals
    • Sterilization in place (SIP) of docked split-valves is possible
    • Suitable for high containment powders and liquids charging
    • Suitable for chemically aggressive powders and liquids
    • PTFE does not shed seal material into the product
    • Less than 1 μg/m3 containment levels are achievable
