Steam Converting Valve (DUV Type C4)
Hydraulic actuator made by Welland.
Fewer interfaces, a perfectly matched valve and actuator system. A single-source solution.
Solid, stepped stem, matched to the seat diameter to prevent deflection in horizontal mounting positions and ensure excellent guiding.
Robust yoke design to prevent deflection in horizontal stem orientations
Low-vibration and low-noise design
validated by in-house CFD analysis
Forged steel body
High turndown ratio
Optimized housing design. Avoidance of material accumulation
- Longer service life, especially during dynamic power plant operation
No thermal shocks in the outlet line due to the prevention of water dropout
Zero thermal shocks in the outlet
- thanks to the centralized flow design of the water/steam mixture right at the motive steam nozzle outlet.
Zero thermal shocks in the discharge line
- achieved by aligning the steam flow toward the center of the outlet piping using a flow straightener.
True two-stage control engineered through a powerful combination of a multi-hole cage and a control cylinder
Minimal maintenance, maximum uptime
all wear parts can be replaced directly on site. Internal components are bolted or slotted into place strictly zero welding required!
Optimum steam conditioning across the entire load range via an integrated motive steam nozzle
- Outlet temperature kept close to the saturation line.
- High water-to-steam ratios easily achievable.
- Short mixing distances for maximum compact efficiency.
- Immediate cooling of even minimal steam quantities.
