Schroedahl Type AC High-Pressure Control Valve with Multi-Stage Axial Flow Limitation
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
Applications
- High-pressure control valve for the power plant and process industry as well as for offshore applications
- Also suitable as pump protection for minimum flow control
- Suitable for the control of the high pressure injection
Nominal Diameter: DN 25–400 / NPS 1-16
Pressure Class: PN 100–640 / Class 600–2500

Function
The AC valve reduces the pressure over multiple controlled stages with different cross-sectional constrictions. As a result, the pressure reduction takes place step by step without cavitation risk and independently of the stroke position. A control range below 5% is usually considered separately. Higher load ranges can also be achieved by combining other contol units (see also the combination valve type AVC).
