This valve opens and closes flow by raising and lowering its stainless‑steel knife disc on a rising‑stem assembly. Actuation options include handwheel, gear‑operated and electric‑actuated versions. Designed for full‑open / full‑closed isolation only, it is not suitable for flow throttling. Equipped with integral PU lining, it delivers dependable shut‑off for abrasive slurries and solid‑laden media, making it well‑suited for heavy‑duty mineral processing and industrial slurry pipeline projects. OEM & ODM orders are welcomed.

Handwheel, Gear operated, Electric actuatedProduct Overview
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.
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.
