Multiblock T Connection fittings with thermostatic valve

The Multiblock T connection fitting is a combination consisting of a thermostatic valve and a connection fitting at the radiator. Thanks to the special AV9U valve insert, the fitting is not only infinitely presettable, but supply and return are also freely selectable, as the flow is possible in either direction. Depending on the version, the connection to the radiator is either with G 3/4 union nut and insert to radiators with G 3/4 external thread (Eurocone) or with G 3/4 union nut and nipple to radiators with G 1/2 internal thread.

The following functions are available: Presetting for hydronic balancing, shutoff as well as draining and filling. Depending on the version, the fitting can be used in two pipe or one and two pipe systems. The Multiblock T connection fitting is available in straight and angle versions and as pivoting version. The fitting is made of nickel plated brass, the centre distance is 50 mm. Design covers are available in various colours and surfaces (see chapter “H-Blocks Accessories and spare parts”)

Multiblock T-RTL Connection fittings with thermostatic valve and return temperature limiter

The Multiblock T-RTL connection fitting is designed for the combined use of radiators and surface temperature regulation in two pipe systems. The fitting includes an AV 9 valve insert with infinitely adjustable presetting for automatic hydronic balancing and an RTL controller for return temperature limitation. The room temperature and return temperature are controlled separately. The fitting is soft sealing to the radiator. Depending on the version, the connection to the radiator is either with G 3/4 union nut and insert to radiators with G 3/4 external thread (Eurocone) or with G 3/4 union nut and nipple to radiators with G 1/2 internal thread.

The following functions are available: Presetting for automatic hydronic balancing, shutoff and return temperature limitation for surface temperature regulation. The connection fitting is available in angle version and is made of nickel plated brass, the centre distance is 50 mm. A mounting aid is included in the scope of delivery. Design covers are available in white and chrome plated (see chapter “H-Blocks Accessories and spare parts”).

Multiflex F H-blocks

The Multiflex H-blocks are designed for the connection of radiators with integrated valve set.

The fittings are soft sealing to the radiator. Depending on the version, the connection to the radiator is either with G 3/4 union nut and insert to radiators with G 3/4 external thread (Eurocone) or with G 3/4 union nut and nipple to radiators with G 1/2 internal thread.

The following functions are available: Shutoff, draining, filling and presetting. Depending on the version, the fitting can be used in two pipe or one and two pipe systems. The Multiflex connection fitting is available in straight and angle versions and as pivoting version. The fitting is made of nickel plated brass, the centre distance is 50 mm.

Inversion fittings

Inversion fittings are connection fittings that are designed for reversed flow and return at radiators with integrated valve set. They ensure a correct flow against the valve insert by exchanging the supply and return flow crosswise. 

The fittings are soft sealing to the radiator. Depending on the version, the connection to the radiator is either with G 3/4 union nut and insert to radiators with G 3/4 external thread (Eurocone) or with G 3/4 union nut and nipple to radiators with G 1/2 internal thread.

All inversion fittings feature a shutoff function. They are available in straight and angle versions and are made of nickel plated brass. The centre distance is 50 mm. Item no. 1016372 has a reduced centre distance to the pipe network (40 mm).
