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
Lightweight structure, low installation cost
The lightweight wafer body of this knife gate valve occupies little pipeline space, easy to install without pipeline modification, effectively cutting construction cost.
Full diameter without material accumulation, not easy to block
Full bore straight flow channel without dead zone, preventing sediment accumulation and valve blockage for slurry and granular media.
Ductile iron is durable and suitable for solid-liquid mixed 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
Q1 What media are suitable for this wafer knife gate valve?
It is ideal for challenging media including municipal sewage, mine slurries, power plant ash, chemical slurries, pulp/paper sludge, and granular or dusty bulk materials.
Q2 How does the knife gate valve prevent clogging?
The valve utilizes a concentric full straight bore design without dead zones or cavities, allowing smooth flow and eliminating medium accumulation and sedimentation.
Q3 Does the valve support bidirectional sealing?
Yes, the valve is engineered for bidirectional flow and provides a zero-leakage sealing performance under normal operating pressures.
Q4 What actuation options are available?
While standard configuration comes with a manual handle/handwheel, optional pneumatic and electric actuators can be equipped for automated process control.
Q5 What is the operating temperature range?
The operating temperature rating is -20°C < T < 120°C, meeting the requirements of most industrial liquid and slurry applications.
Q6 How is the valve packaged for international shipping?
All valves are packed in standard export wooden cases to ensure optimal protection against vibration and moisture during long-distance transit.
