The linear reducing valve VC 50 is designed as a capillary valve. The capillary length and thus the flow rate can be adjusted very precisely via an adjustable slide. This design is ideal for reducing high system pressures, while wear is low due to the laminar flow conditions in the capillary. Another advantage is the long-term stable flow in typical fouling conditions in the water-steam circuit compared to a needle valve.
The valve capillary can be fully opened in a flushing position to remove deposits, and the valve can also be fully closed.
- Robust design
- Linear pressure reduction
without cavitation
- Most accurate flow adjustment
- Suitable up to 400 bar
- Maximum protection
of downstream components
- Low wear
- Closing function without flow
In accordance with VGB guidelines, the pressure of the sample water is reduced after cooling. This prevents, for example, the precipitation of salts and thus ensures representative sampling. Special accessories are available for high requirements in terms of function and safety. In addition, reducing the pressure only when the temperature is lowered massively increases the service life of the valves.
Advantages:
- Pressure reduction up to 400 bar
- Simple and robust design as a needle valve
- Replaceable valve seat for abrasive media
- Differential thread for easy operation
- Adjustment of smallest sample flows due to special corner design of the needle valve
