HERZ DE LUXE VUA-50 designer radiator connection for one-pipe systems, angle, white, M22×1.5, S778444

HERZ DE LUXE VUA-50 M22 Design Radiator Connection for One-Pipe Systems, Angle, White, S778444
HERZ DE LUXE VUA-50 S778444 is a white angle four-way radiator valve for one-pipe heating systems, designed for radiator connection and thermostatic regulation of heating water flow.
The one-pipe version incorporates a HERZ TS-90 continuously presettable thermostatic insert in the return and an integrated bypass, maintaining circulation through the one-pipe heating circuit.
HERZ specifies a 60% bypass flow for this VUA-50 one-pipe configuration, with approximately 40% of the flow passing through the radiator.
The supply valve can be shut off and the return flow can be isolated through the TS valve, simplifying radiator adjustment and servicing.
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 DE LUXE design versions.
The radiator connection is G1/2 with O-ring and the valve is connected by a freely rotating union nut. Heating system pipe connections are M22 × 1.5 with cone.
The supply and return connection centre distance is 50 mm. The angle configuration provides a compact radiator connection according to the pipe layout.
HERZ DE LUXE VUA-50 S778444 is a white design radiator connection for one-pipe systems with an integrated 60% bypass, thermostatic regulation and compact angle configuration.
