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:

TAH, 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

Technical description

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.
