Benefits

Product features
- Two valves in one: the start-up valve and the full load valve combined in a single valve
- Screwed-on housing cover
- The AVC valve uses two throttle bodies on one stem and opens up a much wider range of
application of 1:500
- For the best handling of difficult operating conditions
with extremely high demands on adjustability and high-quality pressure control

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.
