Forged Steel Gate Valve Standard & Engineered Models
TSV manufactures an engineered lineup of Forged Steel 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.
API 602 Bolted Bonnet Forged Steel Gate Valve
Compact forged carbon and stainless body with outside screw and yoke (OS&Y), spiral wound gasket, and hardened 13Cr/Stellite wedge for high pressure auxiliary lines.
Welded Bonnet Fully Sealed Forged Gate Valve
Hermetically seal-welded body-to-bonnet joint engineered for hazardous, toxic fluids, lethal gas lines, and high-vibration power piping.
Integral Flanged Forged Steel Gate Valve
One-piece forged body with integral flanges eliminating welded neck weaknesses, designed for offshore skid piping and severe thermal cycling.
High-Integrity Forged Body Metallurgy & Pressure-Temperature Endurance
Dense ASTM A105 / F316 forged grain structure eliminates porosity risks for severe high-pressure refinery utility manifolds.
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.
