    Material:

    RTL thermostatic head:
    ABS, PA6.6GF30, brass, steel,
    Thermostat filled with an expansible medium.

    Valve body: corrosion resistant Gunmetal
    O-rings: EPDM rubber
    Valve disc: EPDM rubber
    Return spring: Stainless steel
    Valve insert: Brass, PPS
    Spindle: Niro-steel spindle with double O-ring sealing. The outer O-ring can be replaced under pressure.

    Surface treatment:

    Valve body and fittings are nickel-plated.

    Marking:

    THE, flow direction arrow, DN, II+ Designation.

    Colour:

    White RAL 9016

    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.
