HERZ DE LUXE VUA-50 M22 Design Radiator Connection for One-Pipe Systems, Angle, Chrome, S778441

HERZ DE LUXE VUA-50 S778441 is a chrome-plated angle four-way radiator valve for one-pipe heating systems, designed for radiator connection and thermostatic regulation of the heating water flow.

The one-pipe version incorporates a HERZ TS-90 thermostatic insert in the return and an integrated bypass, maintaining circulation through the one-pipe heating circuit while the radiator flow is regulated.

HERZ specifies a 60% bypass flow and 40% radiator flow for this one-pipe VUA configuration.

Both sides can be shut off, simplifying radiator servicing. Thermostatic regulation controls the water flow through the radiator according to room heating demand.

The radiator connection incorporates an immersion tube 290 mm long and Ø 11 mm in diameter.

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

The radiator connection is G1/2, while heating system pipe connections are M22 × 1.5. Compatible HERZ compression fittings are ordered separately.

The pipe centre distance is 50 mm. The angle configuration provides a compact radiator connection according to the installation pipe layout.
