Forged Steel Gate Valve
Product Range
Forged Steel Gate Valve
Flow-Tek Forged Steel Gate Valves are engineered to deliver exceptional strength, dependable sealing, and long-term operational reliability. Designed for demanding high-pressure and high-temperature environments, these valves are ideal for steam systems, oil and gas processing units, power generation facilities, and chemical and petrochemical plants.
All valves are manufactured in accordance with internationally recognized design codes and standards, ensuring complete interchangeability, superior quality, and exceptional workmanship.
Flow-Tek Gate Valves are designed in a rugged Outside Screw and Yoke (OS&Y) configuration with a bolted bonnet construction, rising stem, and non-rising handwheel arrangement. The straight-through bore ensures minimal pressure drop, reduced turbulence, and lower erosion, enhancing overall flow efficiency.Built with advanced engineering features, these valves deliver reliable and cost-effective flow isolation across a broad range of sizes and pressure classes. They are ideally suited for high-pressure, high-temperature services and compatible with a wide variety of industrial fluids.
