Danfoss MNF DN 50 PN 25 — flanged manual (static) double-regulating balancing valve for the main risers and branches of heating and cooling systems. Presetting the handwheel fixes the valve authority so design flow is distributed correctly across the network; the two built-in test plugs allow differential-pressure and flow measurement for commissioning without extra tappings, and the valve doubles as a shut-off. Kvs 53.8 m³/h, maximum differential pressure 200 KPa, media temperature -10 °C to 130 °C, Ductile iron (EN-GJS 400-15) body. OEM P/N 003Z1170. EAN 5710104514628.
