Measures and results

In this application a rubber lined Ramén KSG valve, size 100 mm was installed. After four weeks the steel tube in the outlet from the valve was worn out and replaced with a rubber lined tube. After 12 weeks the valve was inspected and the condition was very near that of a new unused valve.
