The product lists flange connection standards including EN 1092 PN 10, JIS B 2238 10K, ASME/ANSI B16.5 Class 150, AS Table D & E, and BS Table D. During selection, these should match the mating flange standard on site.
Multiple Face-to-Face Dimension Standards
The product's face-to-face standards include the factory standard, TAPPI TIS 405-8, and MSS SP-81, which can serve as a basis for matching installation lengths in existing pipelines.
EN 12266-1 Rate A Sealing Class
The product is specified with sealing class EN 12266-1:2009 Rate A, which can be used as a purchasing and acceptance criterion for shutoff sealing performance.
FAQ
What nominal diameters and maximum working pressures are available for the EBRO 90 knife gate valve?
The valve is available in nominal diameters from DN 100 to DN 600. The maximum working pressure is 10 bar for DN 100 to DN 450 and 6 bar for DN 500 to DN 600. Select according to the actual pipe diameter and confirm that system pressure does not exceed the maximum working pressure for the applicable size range.
Which flange connection standards does the EBRO 90 knife gate valve support?
The valve is compatible with EN 1092 PN 10, JIS B 2238 10K, ASME/ANSI B16.5 Class 150, AS Table D & E, and BS Table D flange standards. During engineering selection, verify consistency between the pipeline flange standard, pressure rating, and connection dimensions.
Which standards can be used to determine the face-to-face dimensions of the EBRO 90 knife gate valve?
The valve's face-to-face dimensions can follow the factory standard, TAPPI TIS 405-8, or MSS SP-81. When replacing an existing valve or planning a pipeline layout, use the project requirements and face-to-face dimensions applicable to the actual model to ensure compatibility with the available installation space.
What is the sealing class of the EBRO 90 knife gate valve?
The valve has a sealing class of EN 12266-1:2009 Rate A. This class specifies test acceptance requirements for valve shell and sealing performance and is suitable for valve selections requiring attention to shutoff sealing performance.
