Characteristics
This manual lug carbon steel knife gate valve is cast from WCB carbon steel with high pressure and medium temperature resistance. Threaded lug structure supports single-side blind installation for pump ports and pipeline ends. Full straight bore avoids sludge and dust blockage. Equipped with simple manual handwheel for reliable cut-off, low failure rate and maintenance cost, widely used for steam, ash and non-corrosive slurry pipelines.
Key Advantages
1. High Strength Material: WCB carbon steel features high mechanical strength, withstands medium temperature and pressure without deformation, suitable for steam and high-temperature ash pipelines.
2. Threaded Lug Design: Allows single-side blind installation, bears pipeline tension, easy to maintain, perfect for pump ports and pipeline ends.
3. Reliable Operation: Simple manual handwheel structure with low failure rate, intuitive operation, minimal maintenance and cost-saving for general cut-off pipelines.
Application Scenarios
The WCB knife gate valve is widely used in power plant ash and desulfurization pipelines, metallurgical slurry lines, heating steam pipes, building material dust conveying, non-corrosive industrial sewage, and pump inlet/outlet cut-off systems.
Packaging & Delivery
Standard export wooden case packaging ensures complete safety during transport.
