    Technical description

    Applications:

    Heating and cooling systems.

    Function:

    Control
    Stepless presetting
    Shut-off

    Dimensions:

    DN 10-20

    Pressure class:

    PN 10

    Temperature:

    Max. working temperature: 120°C, with protection cap or actuator 100°C, with press connection 110°C.
    Min. working temperature: -10°C.

    Materials:

    Valve body: Corrosion resistant Gunmetal.

    Valve insert: Brass, PPS (polyphenylsulphide)
    The complete thermostatic insert can be replaced using the HEIMEIER fitting tool without draining the system.
    Spindle: Niro-steel spindle with double O-ring sealing.

    Surface treatment:

    Valve body and fittings are nickel-plated.

    Marking:

    THE, country code, flow direction arrow, DN and KEYMARK-Designation.
    II+ Designation.
    White protection cap.

    Standards:

    V-exact II valves meet the following requirements:
    – KEYMARK certified and tested to DIN EN 215, series D.
    – the “highly expanded version” and the “standard version” of the specification FW 507 drawn up by the Arbeitsgemeinschaft Fernwärme (AGFW) (Working Group for District Heating).

    Pipe connection:

    The female-threaded version is designed for connection to threaded pipe, or in conjunction with compression fittings, to copper precision steel or multi-layer pipe (only DN 15).
    The male-threaded version, in conjunction with the appropriate compression fittings, permits connection to plastic pipe.
    Versions with Viega press connection (15 mm) with SC-Contur are suitable for copper, Viega Sanpress stainless-steel, and Prestabo steel pipe.

    Connection to thermostatic head and actuator:

    HEIMEIER M30x1,5
