Stainless steel dual plate check valve

The type RF202 dual plate check valve is a check valve manufactured with stainless steel that, in addition to the standard properties of a dual plate check valve, offers corrosion protection and durability.

Our RF202 features a robust wafer-type stainless steel body (CF8M) designed for installation between PN10/16 flanges, where the compact face-to-face length according to EN 558-1, Series 16, ensures easy and space-saving integration into existing piping systems. With a maximum operating pressure of 16 bar, the RF202 is ideally suited for demanding applications in water treatment, the chemical industry, and many other industrial applications.

The RF 202 dual plate check valve has a vulcanized seal design, which is available as standard with EPDM and NBR options.
