four-way mixer ZR 15MA ZR15MA

with exchangeable connections
The CENTRA four way mixer ZR is a robust four way mixer fitting made of high-quality grey cast iron GG20 with control curve in chrome-plated
cyclinder plug (DBP and foreign patents). Hence linear temperature
characteristic in heating flow and backflow increase to avoid boiler
corrosion. Mixer are factory set for boiler flow from the left. Changing possible by simply rotating the mixer shaft.
Technical data:
- Housing: grey cast iron GG 20
- Rated pressure: PN 6
- Medium: heating water or frost and corrosion protection Antifrogen®
N-water mix (max. 50%)
- Temperature range: +2...130°C
- Max. permissible differential pressure: 1.0 bar to DN 80
- Leakage rate: 1% of kvs at max. permissible differential pressure.


System prepressure should not be applied to mixers to avoid an increase of the leakage rate. Otherwise we recommend to check the valves.tile zu
