Product description
The Wey FB Series full bore knife gate valve combines the proven Wey middle flange design with a completely free passage, making it the ideal solution for applications where pipes and valves require regular cleaning with pigs. The full bore design ensures no obstruction in the flow path, allowing pigging operations to pass through without restriction. Specially designed scrapers automatically remove deposits from the gate every time the valve is opened, keeping the valve clean and fully operational with minimal manual maintenance.
Proven Performance Against Biofouling
The FB Series has been installed in numerous plants for thermal sea and lake water utilization, where it has proven highly effective in combating the quagga mussel — an invasive species notorious for fouling pipelines and water intake systems. The self-cleaning scraper mechanism significantly reduces the risk of blockages caused by biological growth, ensuring long-term reliability in challenging water treatment environments.
Built on the Wey Middle Flange Design
The FB Series is built on the well-established Wey middle flange design, combining robust construction with easy installation and maintenance. Its reliable performance across demanding industrial applications makes it a trusted choice for water intake systems, thermal energy plants and other processes where pipeline cleanliness is critical.
