Station Flanged Gate Valve
Description: Refers to the internal diameter of the valve or the pipe it is designed to fit. It is expressed in millimeters (mm) or inches.
Common Values: DN 50 (2 inches), DN 100 (4 inches), DN 150 (6 inches), DN 200 (8 inches), and larger sizes, up to DN 1200 (48 inches) or more, depending on the application.
Feature Benefit: Ensures compatibility with different pipe sizes, enabling the valve to be used in a wide range of applications and pipeline configurations.
Power Station Flanged Gate Valve
The Power Station Flanged Gate Valve is specifically designed for high-temperature and high-pressure applications in power generation facilities and industrial process systems. Manufactured in accordance with international standards, it features a robust pressure-sealed or bolted bonnet design, ensuring reliable shut-off performance under demanding operating conditions.
Constructed from premium-grade carbon steel, alloy steel, or stainless steel materials, the valve offers excellent resistance to high temperatures, pressure fluctuations, and corrosion. The full-port design minimizes flow resistance and ensures efficient fluid transmission. It is widely used in steam, feedwater, condensate, and other critical utility systems where safety and operational reliability are essential.
Designed to meet the requirements of North American and Middle Eastern markets, our power station gate valves comply with relevant ASME, ANSI, API, and customer-specific specifications.
As an experienced industrial valve manufacturer, we provide comprehensive OEM and ODM services tailored to project requirements and regional standards.
