    Maximum limitation of the return temperature,
    Presetting (V-exact II),
    Shut-off,
    Venting

    Dimensions:

    Valve body DN 15.
    The flush box has an overall depth of 60 mm.
    Flexible mounting thanks to variable spacing between flush box and cover of up to 30 mm.
    The cover can compensate for slanted mounting of the flush box of up to 6° on each side.
    See also Dimensions.

    Pressure class:

    PN 10

    Setting range:

    Thermostatic head K:
    6 °C to 28 °C
    Return temperature limiter RTL:
    0 °C to 50 °C

    Temperature:

    Max. working temperature: 90°C
    Min. working temperature: 2°C
    For all Multibox models, ensure that the system supply temperature is suitable for setting up the floor heating system.

    Material:

    Valve body: Corrosion resistant Gunmetal
    O-rings: EPDM rubber
    Valve disc: EPDM rubber
    Return spring: Stainless steel
    Valve insert: Brass, PPS (polyphenylsulphide)
    Spindle: Niro-steel spindle with double O-ring sealing. The outer O-ring can be replaced under pressure.
    Plastic parts of ABS and PA.
    Sensor element: Thermostatic head K with liquid filled sensor. Return temperature limiter (RTL) filled with an expansible medium.

    Surface treatment:

    All models optionally with cover and visible graduation cap in white RAL 9016 or chrome-plated.

    Marking:

    THE, flow direction arrows, II+ Designation.

    Pipe connection:

    Pipe-side G 3/4 adaptor with cone suitable for compression fittings for plastic, copper, precision steel and multi-layer pipe.


    Multibox F

    Applications:

    Floor heating systems, wall heating systems

    Functions:

    Individual room temperature control
    Presetting
    Shut-off
    Venting

    Dimensions:

    Valve body DN 15.
    The flush box has an overall depth of 60 mm.
    Flexible mounting thanks to variable spacing between flush box and cover of up to 30 mm.

    Through a capillary tube, the temperature sensor liquid of the thermostatic head acts on the bellows in the valve adaptor. There is therefore never any change in the appearance of the cover with thermostatic head – irrespective of the installation depth.
    The cover can compensate for slanted mounting of the flush box of up to 6° on each side.
