Schroedahl Type AVC (Combi) High-Pressure Control Valve with Special Dual Valve Combination of the Throttle Body
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 diffi cult operating conditions with extremely high demands on adjustability and high-quality pressure control
Applications
- Start-up control and main boiler feed control
Nominal Diameter: DN 50–500 / NPS 2-20
Pressure Class: PN 100–640 / Class 150–2500

Function
AVC combination valves with internal fittings consisting of axial throttling stages and perforated basket fittings.
Combination valve consisting of a multi-stage high-pressure reducing unit for start-up or low load and a single-stage or multi-stage main control unit. Combining these two valve units in one valve achieves an extremely wide rangeability that was previously only possible with two separate valves. This special solution also replaces the previously customary boiler control operation using two separate valves with a main valve and a start-up valve.
