Forged Steel Gate Valve (Class 800 / API 602) – Flowbiz Exports
High-pressure steam pipelines, oil refineries, and chemical processing skids require zero-porosity isolation valves to withstand high thermal stress and line vibration. Flowbiz Exports Pvt. Ltd. manufactures top-quality Forged Steel Gate Valves, engineered strictly in compliance with API 602 and BS 5352 standards to provide leak-tight positive shut-off in extreme operating environments.
What is a Forged Steel Gate Valve?
Unlike cast valves, a forged steel gate valve is produced through high-pressure forging processes that eliminate internal porosity, voids, and structural weaknesses in the body metal. Featuring an Outside Screw & Yoke (OS&Y) rising stem and a bolted bonnet assembly, it utilizes a solid wedge to isolate fluid flow completely when fully closed, offering minimal flow restriction and minimal pressure drop across the line when fully open.

Key Operational Advantages
- High Structural Integrity: Forged steel body construction provides high tensile strength, making it resilient against hydraulic shock, thermal expansion, and line vibration.
- Low Pressure Drop: Straight-through full port or standard port design minimizes fluid friction, ensuring maximum line efficiency.
- OS&Y Construction: External stem threads remain isolated from corrosive line media, extending thread life and simplifying maintenance lubrication.
- Stellite Hardfaced Trim: Optional cobalt-alloy hardfacing on seats and wedge resists wire drawing, pitting, and high-velocity erosion in steam service.
Target Applications
- High-Pressure Steam Systems: Boiler feed lines, main steam distribution headers, and condensate recovery loops.
- Refining & Petrochemical Plants: Hydrocarbon transfer lines, gas treatment skids, and catalytic cracking units.
- Power Generation & Utilities: High-pressure feedwater systems, turbine bypass loops, and auxiliary gas piping.
