DW/CV Line

These cylindrical cartridges cover a size range from 10 mm to 20 mm and offer the easiest installation: they can be inserted into the application device both in and against the direction of flow.


New: DW15-PR Check Valve

The DW15-PR is fitted with a Pressure Relief valve. It allows a tiny amount of water to flow back when the pressure in the mixing chamber exceeds 20.5 (± 4.5) bar. This immediately reduces the pressure and prevents damage to the faucet. Below 20 bar, the DW15-PR operates as a regular check valve in compliance with EN 13959.

Typical applications include thermostatic mixer faucets undergoing external heat impact, e.g. via thermal disinfection procedures, where very high back pressure may occur.
