ARI CHECKO-V Lift Check Valve (Flanged PN25, Nodular Iron Body)

The ARI CHECKO-V Lift Check Valve with PN25 flanged connections and a nodular iron body is engineered to prevent reverse flow in pipeline systems, protecting pumps, compressors, and control valves from potential damage. This non-return valve uses a vertical lift disc mechanism that responds automatically to pressure changes — allowing flow in one direction and sealing tightly when flow reverses.

Constructed from nodular cast iron (ductile iron), the body provides excellent strength, shock absorption, and durability, making it suitable for a wide range of general-purpose applications. The PN25 pressure rating supports medium-pressure systems typically found in heating circuits, water distribution, and low-to-mid pressure steam systems. The flanged design allows for secure installation and straightforward maintenance, with internal access available for cleaning or servicing.

Manufactured by ARI Armaturen, a leader in industrial valve solutions, the CHECKO-V offers a cost-effective yet dependable solution for ensuring safe and efficient one-way flow control.
