Flanged Butterfly Valve Standard & Engineered Models
TSV manufactures an engineered lineup of Flanged Butterfly 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.
Double-Flanged Large Bore AWWA Waterworks Butterfly Valve
Heavy double flanged construction with integral vulcanized rubber body liner and corrosion-resistant disc edge for municipal raw water transmission lines.
High-Pressure Cast Steel Double Eccentric Flanged Butterfly Valve
Cast carbon steel flanged valve designed for offshore platforms and refinery cooling circuits with high flow capacity and low dynamic torque.
Worm Gear Enclosed Marine Flanged Seawater Butterfly Valve
Nickel aluminum bronze body and Monel trim impervious to marine biofouling and crevice pitting in ballast water and offshore firewater loops.
Electric Intelligent Modulating Double Flanged Butterfly Valve
Equipped with high-precision electric rotary actuator, internal PID controller, and bus communication (Profibus/Modbus) for power station water throttling.
High Temperature Flanged Hard-Faced Metal Seated Butterfly Valve
Hardfaced Stellite seat welded directly into the cast steel body, maintaining zero leak shut-off under severe thermal expansion cycles.
Desulfurization Heavy Rubber-Lined Flanged Butterfly Valve
Thick vulcanized chlorobutyl or hard natural rubber lining designed to endure limestone slurry wear in coal-fired power plant flue gas desulfurization (FGD).
Double-Flanged Rigid Construction & High-Pressure Pipeline Integrity
Full double-flanged body architecture prevents pipe stress transfer to the valve seat, ensuring reliable bi-directional shutoff in heavy industrial piping.
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.
