XB Series
Knife Gate Valve – XB Series
Bidirectional, polyurethane-lined knife gate valve for abrasive slurries, wastewater and industrial process duties across South Africa and Africa.
DN50 – DN1200
Bidirectional
Polyurethane-lined body
Heavy slurry / solids service
Overview
The XB Series is a bidirectional lug-type knife gate valve with a one-piece cast body lined internally with polyurethane. It is designed to resist abrasion and handle slurries, wastewater with solids and industrial effluents, making it ideal for mining and heavy-duty applications.
The full-bore passage ensures large flow capacity with minimal head loss while the reinforced body and seat protection guarantee durability under demanding conditions.
Typical Industries & Applications
- Mining & mineral processing (slurry, tailings, effluent)
- Wastewater & sewage treatment plants
- Chemical and process industries
- Power plants and energy sector effluents
- Sewage and industrial wastewater utilities
- Cement, minerals, bulk material slurry lines
