The EBRO 86 HG is a bidirectional sealing knife gate valve specifically designed for double-direction shutoff requirements. It covers nominal sizes from DN 80 to DN 1200 and achieves sealing rate A per EN 12266-1:2009, with a maximum working pressure of 4 to 10 bar depending on the nominal size. The valve complies with face-to-face standards such as MSS-SP81 and adapts to a wide range of flange standards including EN, ANSI, and JIS, making it suitable for bidirectional differential-pressure pipelines that require reliable sealing and good flow performance.

Selection points
Bidirectional sealing and Rate A sealing class
This knife gate valve offers bidirectional sealing capability with a sealing rate of EN 12266-1:2009 Rate A. It can be selected for pipelines requiring shutoff in both flow directions and should be matched against this sealing rate requirement.
Multi-standard flange connection compatibility
The product supports flange standards including EN 1092 PN 10/PN 16, JIS B 2238 10K, ANSI/ASME B16.5 Class 150, ANSI/ASME B16.47 Class 150 Series A, BS 10 Table D, and AS 2129 Table D/E, and can be matched to the existing pipeline flange standard during selection.
Maximum working pressure graded by nominal diameter
The product covers DN 80 to DN 1200, with the maximum working pressure graded by nominal size: DN 80 to DN 250 at 10 bar, DN 300 to DN 800 at 6 bar, and DN 900 to DN 1200 at 4 bar. The applicable pressure limit must be verified against the actual nominal size during selection.
FAQ
What is the sealing direction of the EBRO 86 HG knife gate valve, and is it suitable for bidirectional media differential pressure?
This HG knife gate valve features a bidirectional sealing design and can be used in pipeline applications that require sealing in both flow directions. Its sealing rate is EN 12266-1:2009 Rate A.
What nominal sizes and corresponding pressure ratings are available for the EBRO 86 HG knife gate valve?
The valve is available in nominal sizes from DN 80 to DN 1200. The maximum working pressure is 10 bar for DN 80 to DN 250, 6 bar for DN 300 to DN 800, and 4 bar for DN 900 to DN 1200. During selection, the actual pipeline working pressure should be matched to the maximum working pressure for the corresponding nominal size.
Which pipe flange connection standards does the EBRO 86 HG knife gate valve support?
The product matches the following flange standards: EN 1092 PN 10, EN 1092 PN 16, JIS B 2238 10K, ANSI/ASME B16.5 Class 150, ANSI/ASME B16.47 Class 150 Series A, BS 10 Table D, and AS 2129 Table D and Table E.
To which standard are the face-to-face dimensions of the EBRO 86 HG knife gate valve confirmed?
The face-to-face dimensions of the product follow the factory standard or MSS-SP81. When integrating with existing pipelines, flange spacing, or replacement valves, the required face-to-face dimensions should be verified against the actual model and application conditions.
What are the features of the EBRO 86 HG knife gate valve in terms of flow and sealing?
The HG knife gate valve offers good flow performance and bidirectional sealing capability, making it suitable for applications where both media flow performance and bidirectional shutoff sealing are required.
