PPR Built-in chrome valve

The THERMALINO PPR chrome valve is a built-in stop valve with a PP-R body that is fused into the pipework and concealed in the wall, leaving only a chrome cover and handwheel on show. It shuts off or regulates hot and cold water to a bathroom, kitchen or apartment. It is rated PN25 and comes in Ø20, Ø25 and Ø32.

The PPR Built-in chrome valve is a concealed stop valve for PP-R water installations, part of the Eternal line. Its PP-R body is fused into the pipework and stays inside the wall. The handwheel and spindle sit inside chrome trim on the finished wall surface, so the valve stays usable without spoiling the look of a tiled bathroom or kitchen. The body is made of prime-grade polypropylene random copolymer (PP-R, type 3), which fuses with THERMALINO PP-R pipes and fittings and gives the joint a long service life. The insert is CW617N brass, a European brass grade with lead content below 2.2%. The valve is rated PN25, with an operating temperature of 70 °C and a maximum of 95 °C, so it can be fitted on both hot and cold water lines. Pressure ratings at higher temperatures are given in the technical data sheet. The valve works by a spindle that moves up and down as the handwheel is turned. When fully closed, the spindle presses on the seat at the base of the T-shaped body and stops the flow. In between, the flow can be throttled. This allows the installer to set the supply to a room as well as isolate it for maintenance or repair. The PPR chrome valve is joined by socket fusion to PP-R pipe of the same diameter: Ø20, Ø25 or Ø32. The PP-R body comes in white, grey or green. It is usually fitted at the water inlet of a bathroom, kitchen or apartment, where the supply must be easy to shut off and the valve must look good.
