Product Introduction

ANSI Stainless Steel Flanged Globe Valves is an essential regulating and shut-off device in industrial piping systems.It controls flow and provides precise throttling by lifting the disc via the valve stem.

Made of high-corrosion-resistant stainless steel with flanged ends, the valve is manufactured strictly to American standards.It features reliable sealing, stable regulation and easy maintenance, widely used in oil, chemical, LNG, power, pharmaceutical and water treatment industries.

As a fully American-standard compliant valve, it can be customized in structure, material and actuation to meet various application requirements, providing a reliable solution for industrial piping systems.

Selection Points

1.Pressure & Temperature: Match working pressure and temperature according to ASME B16.34.

2.Material: Select 304 (CF8), 316 (CF8M) or ultra-low carbon stainless steel based on medium corrosiveness.

3.Seal & Flange: Use metal hard seal and RJ flange for high-pressure, high-temperature or particle-containing service; use RF or FF for general service.

4.Structure: OS&Y for clear position indication and easy maintenance; NRS for space-limited installation.

5.Actuation: Electric or pneumatic for remote/high-frequency operation (US standard explosion-proof); manual for low-frequency local operation.
