The FB200 bi-directional knife gate valve shuts off solids-laden, viscous and abrasive media in industrial pipelines. Unlike uni-directional valves, the FB200 seals reliably in both flow directions. This is a decisive advantage in plants where the flow direction changes or where pressure can act from either side.<\/p>\n\n\n\n
A sharp-edged stainless steel gate plate travels through the medium like a guillotine and cuts fibres, sludge and granulates. In addition, the one-piece wafer body allows quick installation between standard PN10 flanges to EN 1092-1<\/a>. All knife gate valves comply with the Pressure Equipment Directive 2014\/68\/EU<\/a> and carry the CE mark.<\/p>\n\n\n\n The cast iron GG25 knife gate valve is the most economical solution for sewage plants, wastewater, pulp and paper, and power plants. Here, the gate plate is SS304L (1.4306) and the stem SS303 (1.4305). For higher mechanical loads, FERGO also supplies the body in GGG40.<\/p>\n\n\n\n The stainless steel 1.4408 (CF8M) knife gate valve, by contrast, suits chemicals, food processing, pharmaceuticals and aggressive suspensions. In this version, the gate plate is SS316L (1.4404), which offers higher corrosion resistance thanks to its molybdenum content. For extremely abrasive media in mining or cement, FERGO also offers a Hardox gate plate.<\/p>\n\n\n\n FERGO adapts the bi-directional knife gate valve to each application with seven seat materials:<\/p>\n\n\n\n Furthermore, FERGO supplies the gland packing in PTFE, graphite, PTFE+NBR, PTFE+EPDM and PTFE+Viton \u2013 matched to the medium and temperature profile.<\/p>\n\n\n\n The bi-directional knife gate valve suits every application that requires shut-off in both pressure directions:<\/p>\n\n\n\n FERGO stocks the bi-directional FB200 knife gate valve in all material, seat and actuation combinations \u2013 order now in the shop<\/a>. For uni-directional sealing, FERGO offers the FM200 knife gate valve<\/a> in sizes up to DN1200. The dead-space-free FB700<\/a>, in turn, adds a scraping effect to bi-directional sealing. Finally, the FL300 slurry gate valve<\/a> comes with a through-conduit gate plate. For individual configurations, special materials (duplex, Hastelloy, titanium) or special sizes, the FERGO team will advise you \u2013 request a custom solution<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" The FB200 bi-directional knife gate valve shuts off solids-laden, viscous and abrasive media in industrial pipelines.

It is particularly suitable for professional use in industrial plants, power stations, and chemical and wastewater engineering<\/strong>, as it offers a reliable solution even under difficult operating conditions. <\/p>\n With Sizes from DN50 to DN600<\/strong> and a hard-wearing Body<\/strong> made of grey cast iron or stainless steel, this slurry gate valve can be flexibly integrated into a wide range of plant concepts<\/strong>. In addition, the one-piece wafer body<\/strong> enables quick and straightforward installation<\/strong> between standardized PN10 flanges, significantly reducing installation effort and downtime. <\/p>\n A key feature is the double-sealing design<\/strong>, which ensures sealing in both flow directions<\/strong>. This not only increases safety but also significantly expands the range of applications. The gate plate is made of high-quality stainless steel SS304L (1.4306)<\/strong>, while the stem is made of SS303 (1.4305)<\/strong> \u2013 both materials are highly corrosion-resistant<\/strong> and therefore particularly durable. <\/p>\n Whether handling abrasive liquids or viscous or solids-laden media<\/strong>, this slurry gate valve proves itself in day-to-day operation. It is also easy to maintain, which reduces operating costs in the long term. This means operators benefit not only from high functional reliability<\/strong>, but also from efficient overall cost-effectiveness. <\/p>\n Anyone looking to buy a corrosion-resistant knife gate valve<\/strong> that impresses with precision manufacturing, high material quality, and versatile usability<\/strong> is making a future-proof choice<\/strong> with this model.<\/p>\n\n The slurry gate valve \u2013 knife gate valve<\/strong> is an extremely versatile industrial valve<\/strong> that stands out thanks to its high adaptability<\/strong> across a wide range of applications. By using different seat ring materials<\/strong> such as EPDM, NBR, or metallic rings<\/strong>, the valve can be optimally adapted to varying operating conditions<\/strong>. This makes it suitable for both abrasive media and chemically aggressive environments<\/strong>, making it the ideal choice for demanding processes.<\/p>\n In addition, the wide temperature range from -20\u00b0C to +120\u00b0C<\/strong> allows use in numerous industries \u2013 especially in the paper and pulp industry<\/strong>, in power plant engineering<\/strong>, and in the chemical industry<\/strong>. This means the slurry gate valve covers a broad range of applications<\/strong> while offering high operational safety.<\/p>\n Various drive types are available for Operation<\/strong>, allowing the slurry gate valve to be flexibly adapted to the respective plant structure<\/strong>. The selection ranges from manual operation to pneumatic actuators and electric actuators<\/strong>, supporting both simple and automated processes.<\/p>\n Not only the wide range of actuator variants, but also the different packing options<\/strong> contribute to safe, efficient, and maintenance-friendly handling<\/strong>. This makes the slurry gate valve a reliable solution for plants where precise control and high tightness<\/strong> are required. <\/p>\n\nTechnical Data of the FB200 Knife Gate Valve<\/h4>\n\n\n\n
