Product Description
Introduction:
Forged steel check valve is a type of valve manufactured through forging processes, primarily designed to prevent backflow in pipelines and ensure unidirectional flow. Its key characteristics include high strength, high-pressure resistance, and superior sealing performance, making it widely used in industries such as petroleum, chemical, and power generation for high-pressure, high-temperature, or corrosive media applications.
Standard:
Design and Manufacture: BS1868 or API 6D
Inspection and Test: API 598 or API 6D
End flange Dimension: ASME B16.5, ASME B16.47A, MSS SP-44, ASME B16.47B, API 605
Weld End Dimension: ASME B16.25
Face to Face and End to End: ASME B16.10
Ratings: ASME B16.34
Wall Thickness Dimension: API 600 and BS 1868
Feature:
High Pressure Resistance Withstands pressures up to ANSI Class 800~2500 (PN100~PN420), suitable for demanding operating conditions.
Zero-Leakage Sealing Optional metal hard-seal or soft-seal designs, compliant with API 598/ANSI FCI 70-2 standards.
Low Flow Resistance Design Full-bore or reduced-bore structure optimizes fluid efficiency.
High/Low Temperature Resistance Operates in extreme temperatures ranging from -196°C to 600°C, covering LNG, steam, and other harsh environments.
Corrosion Resistance Constructed with stainless steel (SS316), alloy steel (Inconel), or coated surfaces to withstand acidic media.
Low Maintenance Simple structure with no external driving components, ensuring high reliability.
