AC High-pressure CV with multi-stage axial flow
Robust high-pressure control valve with multi-stage axial flow
General information
Product features
- Cavitation-free, multi-stage vortex plug with an axial flow direction under high pressure
- Linear characteristic curve or according to valve design
- Screwed-on housing cover
- Wear free
- Designed for extreme high pressure control and to avoid cavitation damage
- The multi-stage axial plug with vortex system operates in the axial flow direction, is extremely robust and special material combinations enable it to also be used with complex water mixtures and other media
Features and advantages
Pressure reduction via multi-stage controlled, sub- critical expansion is particularly low-noise.
- The valve seat and perforated basket can be replaced
- Large control ratio for control in the start-up range with high differential pressure
- Low-maintenance, adjustable stuffing box (packing pure graphite)
Options:
- Balanced plug
- Armoured sealing surfaces
- Heating and drainage nozzles
Designs according to customer requirements are also available.
All common drive types can be used.
