Application scenarios
Isolation of High-Consistency Pulp Transfer Pipelines
Used for the transfer and isolation of high-consistency pulp in pulp and paper plants, with media concentrations exceeding 5%. The through-going gate can accommodate high-consistency pulp and reliably shut off static media columns. Bidirectional sealing makes it suitable for large-diameter pipelines from DN 300 to DN 900. The maximum working pressure is 10 bar for DN 300 - DN 800 and 6 bar for DN 900.
Isolation of Liquid-Media Process Pipelines
Used for the isolation and shutoff of process pipelines conveying liquid media. The through-going gate provides good flow characteristics, while bidirectional sealing enables reliable shutoff. It is suitable for process isolation in large-diameter liquid pipelines from DN 300 to DN 900.
Isolation of High-Consistency, Solids-Laden Media Pipelines
Used for the isolation and shutoff of pipelines conveying high-consistency media containing solids, as well as at equipment connection points. The through-going gate enables reliable shutoff of high-consistency media and static media columns, provides good flow characteristics, and supports bidirectional sealing for isolation under demanding media conditions.
Isolation of Industrial Waste Transfer Pipelines
Used for the isolation of pipelines conveying media containing solids, such as industrial waste. The product is designed for demanding media, with a through-going gate that maintains good flow characteristics and enables reliable shutoff under high-consistency or static media column conditions. Bidirectional sealing makes it suitable for shutoff in large-diameter pipelines.
Selection points
Through-Going Gate Design for High-Consistency Media
The valve is equipped with a through-going gate that ensures reliable shutoff of high-consistency and static media while maintaining good flow characteristics. It is suitable for demanding media conditions involving pulp with a concentration above 5%, liquids, waste, powder, and dust.
Bidirectional Sealing Capability
This knife gate valve provides bidirectional sealing without strict flow-direction restrictions, making it suitable for piping systems where the flow direction may change or bidirectional shutoff is required.
Differentiated Maximum Working Pressure for Large Diameters
The maximum working pressure is 10 bar for DN 300 to DN 800 and 6 bar for DN 900. The applicable process pressure limit must be checked for the selected nominal diameter.
EN 12266-1 Rate A Tightness Class
The tightness class complies with EN 12266-1:2012 Rate A and can be specified as the shutoff leakage acceptance criterion in a technical purchasing agreement.
Compatibility with Multiple Flange Standards
The valve supports multiple flange standards, including EN 1092 PN 10, PN 16, JIS B 2238 10K, ASME/ANSI B16.5 Class 150, and B16.47 Class 150 series A, facilitating piping interface matching in projects involving different standards and retrofit applications.
FAQ
What media and operating conditions is the EBRO HP knife gate valve suitable for?
The HP knife gate valve is suitable for pulp, liquids, waste, powder, and dust, particularly high-consistency media with pulp concentrations above 5% and static media conditions. The through-going gate helps achieve reliable shutoff while maintaining good flow characteristics.
Does the HP knife gate valve provide bidirectional sealing?
Yes. The HP knife gate valve provides bidirectional sealing and is suitable for piping systems that require media shutoff in both directions. Its through-going gate enables reliable shutoff under high-consistency and static media conditions.
How should the HP knife gate valve be selected based on nominal diameter and pressure?
The HP knife gate valve is available in nominal diameters from DN 300 to DN 900. The maximum working pressure is 10 bar for DN 300 to DN 800 and 6 bar for DN 900. The actual pipe diameter, media conditions, and system pressure should all be verified during selection.
Which piping flange standards are compatible with the HP knife gate valve?
