Characteristics
This DI knife gate valve is made of ductile iron with anti-corrosion coating. Its ultra-thin wafer structure saves installation space. Full straight bore design avoids material accumulation and blockage. Equipped with wear-resistant seat, it provides reliable shutoff for slurry, sewage and granular medium. Manual, pneumatic and electric actuators are optional for automatic control, widely applied in sewage, mining and chemical industries.
Advantages
The lightweight wafer body of this knife gate valve occupies little pipeline space, easy to install without pipeline modification, effectively cutting construction cost.
Full bore straight flow channel without dead zone, preventing sediment accumulation and valve blockage for slurry and granular media.
Ductile iron body of this valve knife features high toughness and impact resistance, wear-resistant seal fits sewage, slurry and dusty medium for long service life.
Packing
Standard export wooden case packaging
Application Scenarios
The knife edge gate valve widely used in municipal sewage treatment, mine slurry transportation, power plant ash pipelines, chemical slurry, papermaking sludge and building material dust conveying systems.
Frequently Asked Questions (FAQ)
It is designed for demanding solid-liquid mixed media, including slurry, municipal sewage, power plant ash, chemical slurry, paper pulp, and granular dust systems.
Yes, this knife gate valve features a bidirectional sealing direction and achieves a zero leakage sealing grade under normal operating conditions.
While standard operation comes with a manual handle, manual, pneumatic, and electric actuators can be equipped for automated system integration.
The valve operates reliably within a working temperature range of -20°C < T < 120°C.
The full straight bore design leaves no dead zones within the flow channel, allowing unobstructed passage of slurries and sediments without accumulation.
