The stainless steel disco check valve type RV108 is a wafer check valve stainless steel 1.4408 with metallic seat for industrial piping systems. The body is manufactured in stainless steel 1.4408 (CF8M). The disc is also 1.4408 (CF8M). The spring is 1.4301. The stainless steel disco check valve is available with disc seal in NBR, EPDM, Viton or metal. The stainless steel wafer check valve DN200 covers nominal sizes DN15 to DN200 in pressure rating PN40 and mounts between PN16, PN40 or ANSI Class 150 flanges. The maximum operating pressure is 40 bar up to DN80 and 25 bar from DN100. Face-to-face length follows EN 558-1<\/a> Series 49. The operating temperature range is \u221220 \u00b0C to +200 \u00b0C. FERGO supplies the check valve 1.4408 ex stock.<\/p>\n\n The stainless steel disco check valve is available in nominal sizes DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150 and DN200. The pressure rating is PN40. The maximum operating pressure is 40 bar for DN15 to DN80 and reduces to 25 bar for DN100 to DN200. The wafer body mounts between mating flanges PN16, PN40 or ANSI Class 150. The face-to-face length to EN 558-1 Series 49 is the standardised short length for disco check valves. The compact wafer design reduces installation space and weight compared to flanged check valves. The spring-loaded disc prevents backflow of liquids and gases reliably in both horizontal and vertical installations.<\/p>\n\n The body of the stainless steel disco check valve is manufactured in 1.4408 (CF8M) for high corrosion and chemical resistance. The disc in 1.4408 provides the same media resistance as the body. The spring in 1.4301 ensures reliable closing of the disc. The metallic seat provides a durable seal even at high temperatures up to +200 \u00b0C and pressures up to PN40. The disc seal in NBR is suited for oils, compressed air and neutral media at temperatures from \u221220 \u00b0C to +80 \u00b0C. The EPDM version handles water, aqueous solutions and air. For chemically aggressive media and elevated temperatures, the Viton seal is available. For very high temperatures or metal-compatible media, the metal seal offers the highest resistance.<\/p>\n\n The stainless steel disco check valve protects pipelines in chemical processing, power generation, food and pharmaceutical production and general process engineering. The disco check valve PN40 handles liquids, gases and steam. The compact wafer design simplifies installation in existing pipelines and reduces space requirements. The choice of disc seal depends on medium and temperature \u2014 NBR for oils and compressed air, EPDM for water and air, Viton for chemicals, metal for high temperatures and pressures.

Applications and Ordering<\/h3>\n\n
Disco check valves for liquids and gases<\/h2>\nThe Disco check valve RV108 is a versatile and reliable solution for a wide range of industrial applications. It is available in sizes DN15 to DN200 and is suitable for installation between flanges up to PN16\/40 and ANSI150. The Body, Disc and Spring are made of robust CF8M (SS316), while the Seat is metal, ensuring high resistance and durability. The valve has a face-to-face dimension in accordance with EN 558-1, Series 49, and can be used at operating temperatures from -20\u00b0C to +200\u00b0C. The maximum operating pressure is 40 bar; from DN100 it is 25 bar. These features make the RV108-SSMFW ideal for use in demanding environments where reliability and performance are critical.
