Fixed area nozzle(s)
DV1 Venturi
Description
Simple construction
- Fixed-area spray nozzle
- For small line size with an upstream steam pressure- reducing valve (PRV)
- Relies on the energy of steam ow for atomization
Typical applications
- Process steam desuperheater downstream of existing steam PRV
- Small PRDS
DVL Low-Loss Venturi
Description
- Simple construction
- High spray water pressure is not required
- For small line size with or without an upstream steam PRV Relies on the energy of steam ow for atomization
- High rangeability
Typical applications
- Process steam desuperheating
- Small PRDS
Ideal for applications where pressure drop in steam line has to be kept low
