- Destination: Germany
- Target sector: Pulp and paper industry
- Valves: 1 pc. in DN 50
- Special feature: Piston-controlled, intermediate piece, high reduction ratio
In a paper mill, the DM 511ZK pressure reducing valve was installed in a condensate line just upstream of the feed water tank. There, the valve regulates the pressure from 30 bar down to 2.8 bar. This is easily possible thanks to the piston control and the reduction ratio of 19:1.
In addition to the increased inlet pressure, the temperature of the medium at 234 °C should not be underestimated. To protect the control unit, the valve is fitted with an intermediate piece and requires a corresponding water seal. As a rule of thumb, 1 mm of water seal reduces the temperature by 1 °C. This means that the valve can be used up to 350 °C.
