WEY-VM Stock Series
Spherical-disc knife gates for pulp stock lines, slurry transport, and fiber-rich flows. Shear-edge design prevents fiber wrap and packing.
The original spherical-disc knife gate — engineered for slurries, dewatering, fly ash, and the abrasive applications where standard knife gates fail.
WEY Valves invented the spherical-disc knife gate design — and remains the gold standard. Where flat-disc knife gates struggle with packing, fiber wrap, and abrasive wear, the spherical disc geometry shears cleanly through stock and slurry, resists packing, and delivers true bubble-tight shutoff on solids-laden flows.
Manufactured in Switzerland with the engineering rigor that name implies, WEY knife gates serve pulp & paper mills, mining operations, power plants, and steel mills across North America and the world. Available with urethane lining, replaceable wear sleeves, and a full range of actuation packages.
Miller Valve has partnered with WEY for decades to serve customers in the most abrasive applications industry has to offer. Stocking inventory, engineering support, and same-day quotes backed by 30+ years of mill, plant, and mine experience.
