Flowrox Pinch Valve Improves Reliability of Lime Control

Vattenfall Energy decided to use Flowrox pinch valve which improves lime control reliability. Flowrox has over 4 000 successful installations in the energy industry. From solutions for demanding shut-off, control to pumping applications. Flowrox valves are known to boost productivity by improving process efficiency and extending service intervals.

Vattenfall Energy, located in Denmark, wanted to improve the performance of the existing valve process conditions in their FGD (Flue gas desulphurization) lime slurry control feeding system. The process originally had a special control valve with a ceramic trim system installed and service time for this valve was typically around 6 to 9 months. After a meeting with Scanrox, an official Flowrox representative in Denmark, the customer decided to replace the old valve with new Flowrox PVE 50 mm pinch valve to improve lime control reliability .

After the installation of the first Flowrox valve, the reliability was significantly higher. One year after, another Flowrox valve (PVE 65 mm) was installed. As a result of the pinch valve replacing the old ceramic valve, service interval was extended to more than 24 months without any disturbances in the lime slurry control.

Key benefits

Excellent wear resistance

Only the inside sleeve in contact with the medium.

Extended service interval

Sleeve lifetime was extended to more than 2 years.

Low maintenance cost

Inside sleeve is the only replaceable part.
