The heavy‑duty carbon‑steel body adopts a one‑piece reinforced frame structure. A precision‑polished 304 stainless‑steel knife disc paired with high‑wear integral PU lining offers excellent abrasion resistance and positive bi‑directional sealing performance.
The rising-stem design ensures stable linear motion for reliable open-close operation.
- Handwheel: Direct manual operation for on-site adjustment.
- Gear‑operated: Reduced operating effort for large-size valves.
- Electric‑actuated: Motor-driven control for remote automation.
All actuation versions use a simple, robust mechanical structure for easy operation and maintenance.
- ENVIRONMENTAL ADAPTABILITY
It retains reliable sealing and smooth cyclic performance under heavy‑duty abrasive slurry service, with a maximum working temperature of 80°C.
Manufactured in strict accordance with MSS SP‑81, flange dimensions comply with ASME B16.5 150LB for compatibility with global industrial piping systems.
Featuring field‑validated knife‑gate construction, this valve serves a wide range of applications including mining, mineral processing, power‑plant ash handling, wastewater treatment and pulp & paper industries.
- Wear‑resistant PU lining shields the valve body against erosion from abrasive solid‑laden media
- Precision‑machined stainless‑steel knife disc shears slurry particles and lowers the risk of jamming
- Multiple actuation selections: handwheel, gear‑operated and electric‑actuated to satisfy varied site operating demands
- Robust one‑piece frame engineered for long‑term heavy‑duty slurry‑service conditions
