ARI CHECKO-D Check Valve (Wafer Pattern, Stainless Steel Body)

The ARI CHECKO-D Check Valve with a wafer pattern design and a stainless steel body is a space-saving, corrosion-resistant solution for preventing reverse flow in pipelines carrying steam, gas, or liquid media. Its dual-plate swing mechanism allows forward flow with minimal pressure drop, and closes quickly upon flow reversal — protecting downstream equipment such as pumps, compressors, and heat exchangers.

The wafer-style body is designed for easy installation between flanges, significantly reducing space requirements and weight compared to flanged alternatives. Made entirely from stainless steel, the valve offers outstanding resistance to corrosion, erosion, and thermal stress, making it ideal for aggressive process media or hygienic applications. This check valve is suitable for horizontal or vertical mounting and can be used across a wide range of industries, including food processing, chemical manufacturing, marine, and clean steam systems.

Manufactured by ARI Armaturen, the CHECKO-D delivers dependable non-return protection, excellent sealing performance, and long-lasting durability in a compact, efficient form.
