The ebro D2G is a full-bore bi-directional sealing knife gate valve designed specifically for vertical pipeline installation. Built to Stafsjö factory standards, it features two hard-chrome-plated gate plates moving toward each other for fast open-close operation, with nominal sizes from DN 100 to DN 600 and compatibility with a wide range of international flange standards including EN, JIS, and ASME. With excellent flow capacity and bi-directional sealing performance, it is particularly suitable for pulp and paper, industrial wastewater, and sludge treatment systems, effectively addressing the line isolation challenges of contaminated media or waste containing fibers and impurities.

Application scenarios
Pulp and Paper Waste Line Isolation
For isolation of contaminated waste lines containing fibers, impurities, or screen rejects in pulp and paper systems. With its full-bore design, bi-directional sealing, and two hard-chrome-plated gate plates moving toward each other, the D2G is well suited to contaminated media or waste handling and must be installed in vertical pipelines.
Industrial Wastewater and Sludge Treatment Line Isolation
For isolation of vertical process lines carrying industrial wastewater, sludge, or other contaminated media. The D2G's full-bore design, bi-directional sealing, and hard-chrome-plated gate plates moving toward each other make it well suited to contaminated media or waste handling; installation orientation is vertical pipeline.
Selection points

FAQ
What design does the D2G knife gate valve use to achieve bi-directional sealing and fast operation?
The D2G features two hard-chrome-plated gate plates moving toward each other together with a full-bore bi-directional sealing design. The counter-moving dual gate plates enable fast operation, while the full-bore flow path allows media to pass through smoothly.
What media handling applications is the D2G knife gate valve suitable for?
The D2G's shut-off performance and flow characteristics make it particularly suitable for contaminated media or waste handling applications. Final selection should be confirmed against actual media characteristics, pipe diameter, and working pressure.
What are the installation orientation restrictions for the D2G knife gate valve?
The D2G is suitable only for vertical pipeline installation. Piping layouts should include pipe sections that meet vertical installation requirements, and the valve must not be used in non-vertical pipeline positions.
What nominal sizes and corresponding maximum working pressures are available for the D2G knife gate valve?
The D2G is available in nominal sizes from DN 100 to DN 600. DN 100 to DN 400 have a maximum working pressure of 10 bar, while DN 500 to DN 600 have a maximum working pressure of 6 bar.
Which flange connection standards does the D2G knife gate valve support?
The D2G supports EN 1092 PN 10, JIS B 2238 10K, ASME/ANSI B16.5, and ASME/ANSI B16.47 Class 150 Series A flange connection standards; face-to-face dimensions follow the Stafsjö factory standard.
