Knife Gate Valve Standard & Engineered Models
TSV manufactures an engineered lineup of Knife Gate Valve configurations for global oil & gas transmission pipelines, refinery manifolds, power plants, and severe industrial processes. Each unit undergoes 100% hydrostatic and pneumatic factory acceptance testing before dispatch.
Heavy Slurry Hydraulic Actuated Knife Gate Valve
Heavy-duty hydraulic cylinder actuation engineered to shear through consolidated tailings and dense ore mineral slurries without stalling.
Sprocket Chain-Operated Slurry Knife Gate Valve
Designed for overhead pipe bridges and elevated conveyor chutes, operated reliably from ground level with heavy industrial link chain.
Pneumatic Stainless Steel Automated Knife Gate Valve
Equipped with dual magnetic limit switch box, 5/2-way Namur solenoid, and air filter regulator for high-cycle automated bulk powder batching.
Wafer & Lug Bi-Directional Knife Gate Valve
Zero downstream leakage in both flow directions with perimeter reinforced elastomer seat ring for pulp stock, wastewater, and dry bulk.
Field-Replaceable Rubber Seat Slurry Knife Gate Valve
Features twin heavy-duty molded rubber sleeves that push together under line pressure, completely protecting metal body from slurry wear.
Manual Handwheel Industrial Knife Gate Valve
Classic rising stem design with brass yoke bushing and precision acme stem threads for smooth manual throttling in wastewater treatment.
Beveled Stainless Knife Shearing Action & Heavy Slurry Deflection
Self-cleaning gate geometry shears through heavy pulp, mineral slurry solids, and fiber clumps without seat jamming.
100% Hydrostatic Acceptance
Every valve is pressure-tested per API 598 / API 6D Rate A with zero allowable bubble leakage prior to factory crating.
EN 10204 3.1 Certified
Certified Mill Test Reports (MTR) with optical emission spectrometer chemical composition and mechanical impact values.
Global OXY Approved Supplier
Audited and approved on the global master vendor list (#24) of Occidental Petroleum for severe upstream duties.
