The dual plate check valve type RF200 is a compact, spring-loaded wafer non-return valve for industrial piping systems. Two semi-circular discs open with flow and close within fractions of a second on flow reversal \u2013 providing effective water hammer protection and pressure surge prevention.<\/p>\n
Key technical data:<\/p>\n
The vulcanised sealing surface ensures a durable, dimensionally stable seal \u2013 even with frequent closing cycles and varying pressure conditions.<\/p>\n
The dual plate check valve RF200 is available from stock at Fergo<\/a> in all nominal sizes. For higher corrosion resistance, Fergo offers the dual plate check valve RF202<\/a> in full stainless steel. As a single-disc alternative with a wider range of materials and seat options, the wafer check valve RK100<\/a> is available.<\/p>\n","protected":false},"excerpt":{"rendered":" Dual Plate Check Valve RF200 \u2013 Spring-Loaded Backflow Prevention in GGG40 The dual plate check valve type RF200 is a compact, spring-loaded wafer non-return valve for industrial piping systems.

This type of check valve is used because it has low flow resistance, thus minimizing pressure loss. They are also suitable for large volume flows of liquids and gases in industrial applications. \n\nOur RF200 features a wafer-type body specifically designed for installation between PN10\/16 flanges. With a Face-to-face dimension according to EN 558-1, series 16, this dual plate check valve is compact, space-saving, and can be easily integrated into existing piping systems. The Body of the RF200 is made of robust GGG40 (EN-GJS-400-15), while the plates are made of corrosion-resistant stainless steel (CF8M), and the shaft and Spring are also made of stainless steel. Thanks to the spring-loaded plates, the valve closes quickly, which is important to prevent water hammer or other damage caused by sudden pressure changes. \n\nThe RF200 dual plate check valve is designed for high loads, thus offering durability and efficiency. This valve is available with vulcanized EPDM and NBR seals. \n\nDual Plate Check Valve RF200-D2SEFW (Item No.: 302-1020-xx) DN50 DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300<\/strong>\n
