ARI CHECKO-V Lift Check Valve (Flanged PN40, Cast Steel Body)

The ARI CHECKO-V Lift Check Valve with PN40 flanged ends and a cast steel body is a high-performance non-return valve designed to prevent reverse flow in steam, gas, and liquid pipelines. Its vertical lift mechanism allows flow in one direction while automatically closing when reverse pressure is detected, safeguarding equipment such as pumps, compressors, and control valves.

Built with a durable cast steel body, this valve offers excellent strength, thermal resistance, and long-term reliability — even in demanding process environments. The PN40 pressure rating ensures safe and consistent operation in high-pressure applications, making it suitable for steam systems, power plants, chemical processing, and industrial utilities. The flanged connections allow secure installation, easy maintenance access, and full compatibility with standard pipeline systems.

Designed and manufactured by ARI Armaturen, the CHECKO-V combines German engineering precision with robust functionality, making it a trusted choice where performance and protection are critical.
