Gate Valves
Heavy-duty gate valves for full-bore isolation in the most demanding pipeline and process environments. Designed for high-temperature, high-pressure service with zero-leakage performance.
Gate Valve Types
From standard wedge gate valves to specialist expanding and knife gate designs — engineered for reliable isolation across all operating conditions.
Wedge Gate Valves
Flexible and solid wedge designs for reliable isolation in high-temperature and high-pressure service. Available in bolted bonnet and pressure seal configurations.
Slab Gate Valves
Single-piece gate with through-conduit design for pipeline pigging applications. Self-cleaning cavity prevents debris build-up in the body.
Expanding Gate Valves
Mechanically expanding gate provides positive upstream and downstream sealing. Ideal for critical isolation in pipeline block valve stations.
Knife Gate Valves
Sharpened gate edge cuts through thick media and slurries. Designed for pulp & paper, mining, and wastewater applications requiring zero blockage.
