Features
- Desuperheating with innovative seat injection in the turbulent zone at all load cases.
- Extremely short evaporation length with uniform temperature distribution.
- Protection of downstream pipe against thermal shock and erosion.
- Flow optimized design of the body.
- Pressure reduction by multi-stage-controlled expansion ensures lowest sound pressure
- levels and extremely low vibrations.
- Water injection area is controlled by the movement of the valve plug and subsequently the delta p tends to be constant for good atomization.
- Quick change valve internals.
- Spring-loaded packing for long term leak-tightness.
- Multiple customized options.
