HERZ DE LUXE VUA-50 M22 Design Radiator Connection for Two-Pipe Systems, Angle, Matt Black, S768449

HERZ DE LUXE VUA-50 S768449 is a matt black angle four-way radiator valve for two-pipe heating systems, designed for radiator connection and thermostatic regulation of the heating water flow.

The valve incorporates a HERZ TS-98-V continuously presettable thermostatic insert in the return, allowing precise radiator flow adjustment and hydraulic balancing of the heating system.

The two-pipe version is designed without a bypass. The supply side can be shut off, while the return flow can be isolated through the TS thermostatic valve.

The radiator connection incorporates an immersion tube 290 mm long and Ø 11 mm in diameter, providing the required flow path inside the radiator.

The thermostatic head connection is M28 × 1.5, suitable for compatible HERZ thermostatic heads, including the matt black HERZ DE LUXE design thermostatic head.

The radiator connection is G1/2 with O-ring seal. Connection to the radiator is made using a freely rotating union nut for easier installation.

Heating system pipe connections are M22 × 1.5 with cone for suitable HERZ compression adapters. The supply and return pipe centre distance is 50 mm.

For the HERZ VUA series, maximum operating temperature is 120 °C, maximum operating pressure is 10 bar and maximum differential pressure in thermostatic operation is 0.2 bar.

HERZ DE LUXE VUA-50 S768449 in matt black is intended for design radiators and interiors where the radiator connection fittings should match a black decorative finish.
