The EBRO MV knife gate valve is an industrial valve designed for isolating liquid and dry media. It features a beveled-edge disc that is pushed against the seat when closing to form a seal. Nominal sizes range from DN 50 to DN 1600, and the valve can be fitted with manual, pneumatic, electric, or hydraulic actuation. It is used for media isolation in pulp and paper, wastewater sludge, biomass, powder, and industrial waste conveying lines.

Application scenarios
Pulp stock line isolation in paper pulping
The MV knife gate valve is suitable for isolating pulp media in paper pulping processes. The product documentation explicitly states its suitability for pulp; the valve uses a beveled-edge disc to cut through the media, and when closing the disc is pushed against the seat to achieve a tight, reliable seal.
Sludge conveying line isolation in wastewater treatment
The MV knife gate valve is suitable for isolating sludge media in municipal and industrial wastewater treatment systems. The product documentation explicitly states its suitability for sludge; the disc cuts through different media and is pushed against the seat when closing to achieve a tight, reliable seal.
Isolation of biomass and powder media conveying
The MV knife gate valve is suitable for conveying and isolating dry media such as biomass and powder. The product documentation explicitly lists biomass and powder among the suitable media; the valve uses a beveled-edge disc to cut through the media and achieves a tight, reliable seal when closed.
Media isolation in industrial waste treatment and conveying
The MV knife gate valve is suitable for isolating media during industrial waste treatment and conveying. The product documentation explicitly states its suitability for different types of waste, both liquid and dry media; when closing, the disc is pushed against the seat to achieve a tight, reliable seal.
Selection points
Beveled-edge disc shut-off with multi-media suitability
The MV features a beveled-edge disc that is pushed against the seat when closing to form a seal. It can be used for liquids and dry media, including pulp, sludge, biomass, powder, and waste.
Nominal size coverage from DN 50 to DN 1600
The nominal size range of this model is DN 50 to DN 1600, allowing selection to match the pipeline diameter.
Compatibility with multiple flange standards
The product supports flange connection standards including EN 1092 PN 10 and PN 16, ASME/ANSI B16.5 Class 150, ASME/ANSI B16.47 Class 150 Series A, JIS B 2238 10K, AS 2129 Table D and E, and BS 10 Table D.
Multiple manual and automatic actuation options
The MV can be equipped with a handwheel, ratchet wrench, chainwheel, bevel gear, pneumatic actuator, electric actuator, or hydraulic cylinder, selectable according to operation and control requirements.
Standard-defined shut-off leakage class
The leakage class is EN 12266 Leakage Rate A and ISO 5208 Class A, which can be used as a selection criterion for shut-off leakage acceptance.
Maximum working pressure segmented by nominal size
The maximum working pressure is specified in segments by nominal size: DN 50 to DN 125 at 16 bar, DN 150 to DN 300 at 10 bar, DN 350 to DN 600 at 6 bar, and DN 700 to DN 1000 at 4 bar.
FAQ
What sealing principle does the EBRO MV knife gate valve use, and why is it suitable for dry media?
The MV knife gate valve features a beveled-edge disc. When closing, the disc is pushed against the seat to form a tight, reliable seal. This closing action helps cut through different media, so in addition to liquids, the valve is also suitable for dry media such as pulp, sludge, biomass, powder, and various types of waste.
How do the nominal sizes of the MV knife gate valve correspond to the maximum working pressure?
The nominal size range of the MV knife gate valve is DN 50 to DN 1600. The listed maximum working pressures are specified in segments by nominal size: DN 50 to DN 125 at 16 bar, DN 150 to DN 300 at 10 bar, DN 350 to DN 600 at 6 bar, and DN 700 to DN 1000 at 4 bar. Pressure parameters for sizes above DN 1000 are not listed in the currently available documentation on this site and must be confirmed against the actual model and application conditions.
What manual or automatic actuation options are available for the MV knife gate valve?
The MV knife gate valve can be configured with manual operation options such as a handwheel, ratchet wrench, chainwheel, or bevel gear, and can also be driven by a pneumatic actuator, electric actuator, or hydraulic cylinder to meet different requirements for on-site operation, remote control, or automation systems.
Which flange standards can the MV knife gate valve be connected to?
The MV knife gate valve is available with flange connections compatible with EN 1092 PN 10, EN 1092 PN 16, ASME/ANSI B16.5 Class 150, ASME/ANSI B16.47 Class 150 Series A, JIS B 2238 10K, AS 2129 Table D and Table E, and BS 10 Table D. When selecting the valve, verify the pipe flange standard against the actual valve specifications.
What is the leakage class of the MV knife gate valve?
The leakage class of the MV knife gate valve is EN 12266 Leakage Rate A and ISO 5208 Class A, suitable for liquid and dry media isolation duties where shut-off sealing performance is required.
