Toshikatsu Umehara –
As a plant maintenance engineer with over a decade of experience in industrial steam and fluid systems, I can confidently say that the KLINGER Grey Cast Iron Piston Valve KVN (DN 125, PN 16) has exceeded our expectations for reliability and performance.
From installation, the flanged end connection (DIN, EN1092-2) made integration into our existing pipeline straightforward and secure. What truly stands out is the valve’s robust construction—grey cast iron EN-GJL-250 ensures excellent durability and corrosion resistance, which is vital for our demanding operational environment.
The pressure-balanced piston design, combined with three elastic KX-GT valve rings, delivers exceptional sealing performance. We’ve experienced zero leakage, even under fluctuating pressures and temperatures, thanks to the valve’s tightness rating (leakage rate A per EN 12266-1). Its ability to handle temperature shocks and alternating steam/condensate cycles without maintenance downtime has saved us both time and money.
What I appreciate most is the low maintenance requirement. The valve can be serviced inline, eliminating the need to remove it from the piping system—a significant advantage during scheduled maintenance. The self-cleaning effect of the piston design has prevented seat erosion and kept the valve operating smoothly, even with media containing particulates.
In summary, the KLINGER KVN piston valve is a tried-and-tested solution that delivers reliable tightness, longevity, and operational efficiency. I would recommend it to any facility looking for a cost-effective, high-performance valve for demanding industrial applications.
