Piston Check Valve - CHECKO V | ARI

The ARI-CHECKO®-V Piston Check Valve is a versatile and robust solution designed for various industrial applications. It is available in multiple configurations, including straight-through and angle patterns with flanges, as well as Y-patterns with flanges or butt weld ends. The valve is constructed from high-quality materials such as grey cast iron, SG iron, cast steel, stainless steel, and forged steel. It features stainless steel or copper-based seat rings and high-quality stainless steel springs. The valve supports pressure ratings of PN6, PN16, PN25, and PN40, and offers both metallic and PTFE-soft sealing options for enhanced leak prevention. It is ideal for systems with high flow turbulences, pressure reduction stations, and compact plants, especially where flow stabilization is challenging or large valve diameters are used. Installation options include flanged or butt weld ends, compliant with DIN EN 12627 standards.
