Flush-mounted valve GRZ CHROM 20 WT Wavin PPR 3072118

Concealed valve for central heating and domestic hot water systems

This Wavin PPR concealed valve is a reliable solution for installation in heating and water systems made of polypropylene (PP). Designed for concealed mounting, it provides an aesthetic appearance and easy access for adjustment. Pressure class PN 20 guarantees safe operation in standard domestic systems.

Design and application

The valve made of high-quality polypropylene has welding spigots, ensuring a tight and durable connection with PPR pipes. Its design allows for smooth flow control, and the handwheel provides convenient operation. It is ideal for installation in walls or other structural elements of the building where discreet valve placement is required. The nominal diameter DN 20 corresponds to the most commonly used dimensions in domestic installations.
