VIEGA Corner Stop Valve 1/2″×3/8″ for In-Wall Cistern 3H/3L — Art. 799779

Description

The Viega Eckventil (art. 799779) is a brass corner (angle-stop) valve for Viega’s concealed in-wall flush cisterns — specifically models UP-Spülkasten 3H and 3L, referenced as model 8580.63. It provides an isolating water-supply valve at the cistern inlet, enabling service or replacement of the cistern without shutting off the main building supply.

The inlet thread is R 1/2″ and the outlet is R 3/8″. The valve spindle carries left-hand thread for the original handle, and the all-brass construction ensures long-term corrosion resistance in damp in-wall conditions. Suitable as a replacement or service part for existing Viega in-wall cistern installations.
