completeline_valves_en_img_3.jpg  Mixproof Valves
Mixproof valves are an essential part of sanitary flow processing,
separating two different products, but also preventing
product contamination from other non-sanitary fluids. Mixproof
means no mixing of incompatible liquids,
but when thinking in terms of processing, the task is to obtain
mixproof solutions while at the same time using as
few resources as possible.
In effect, one double-seat valve can do the job of two or three
single-seat valves, saving you space and installation costs, and
providing you with unmatched system flexibility.
Alfa Laval offers several mixproof valves, all with simple and
cost-effective maintenance.

    Aseptic Diaphragm Valves
    Aseptic Diaphragm Valve
    Alfa Laval offers an extensive range of aseptic diaphragm valves
    for ultra-hygienic processes. The diaphragm valve is the most
    commonly used valve in the pharmaceutical industry, but it is also
    an ideal alternative for other aseptic applications.
    The Alfa Laval Aseptic Diaphragm Valve is a weir type diaphragm
    valve. With its modular design, composed of: valve body,
    diaphragm and actuator, it enables the realization of special
    designs and needs with high quality and well-proven standard
    components. It can be combined in a number of configurations
    and executions but the most typical is a two-way valve offering an
    on/off function.
    The Aseptic Diaphragm Valve is available both with manual and
    pneumatic actuators with a number of options.
     The diaphragm is the critical part of the valve. In the Alfa Laval
    range there are both soft and hard compounds each suitable
    for their specific applications. The soft material diaphragm is
    EPDM which also is available in EPDM with a Kevlar core when
    extra mechanical stability is required. The hard diaphragm is
    PTFE with either EPDM or Silicone as a backing plate.
    For the pneumatic actuators Alfa Laval also offers an externsive
    range of automation units, including control units, position
    indicators, seal adjusters and stroke limiters.
    Apart from the standard two-way valve Alfa Laval also offers
    tank outlet valves, T valves and GMP/SAP valves in a wide

     Regulating Valves
    CPM-2 – Constant Pressure Modulating Valve
    The Alfa Laval air-actuated CPM-2 valve series is designed to
    maintain either constant inlet or constant outlet pressure
    – important for such applications as pasteurization, separation,
    filling systems, filters, filtration and heat exchangers.
    Inside, a diaphragm/valve plug system reacts immediately to
    any alteration of product pressure and changes position so
    that the pre-set pressure is maintained. The valve operates
    with a pressure-regulating valve for the compressed air and
    a pressure gauge in the product line.
    The optimum body design of the CPM-2 results in several
    product benefits, such as excellent cleanability. As the inlet is
    tangential to the bottom of the valve body there is no sump.
    One special plug allows very low capacities and high CIP flow.

    SPC-2 – Sanitary Electro-Pneumatic Modulating Valve
    The SPC-2 is a sanitary valve for use in stainless steel pipe
    systems. Typical applications are automatic control of pressure,
    temperature, flow rates and tank levels. The combination

    Other Valves

    LKC-2 – Non-Return Valve
    The non-return valve LKC-2 is designed for use in stainless
    steel pipe installations to prevent reverse product flow. LKC-2
    opens when the pressure below the valve plug exceeds the
    pressure above the plug and the spring force. It closes when
    pressure equalization has been achieved. A higher counter
    pressure will press the valve plug against the seat.
    MH – Shutter Valve
    The MH is a self-draining valve that allows for multi-directional
    flow of product. An internal shutter closes ports progressively
    to help minimize pressure shock and stress. The MH can either
    be manually or pneumatically operated, and is available with
    two or three port connections at the same level.
