High-Temperature Steam Stainless Steel Flanged Gate Valve

The Stainless Steel Flanged Gate Valve is a robust isolation valve designed for demanding industrial applications, particularly those involving corrosive media, high-temperature service like steam, and general fluid control. Utilizing high-grade stainless steel, this valve offers excellent corrosion resistance and reliable on/off functionality.

Product Overview

This valve features a wedge gate structure and an Outside Screw and Yoke (OS&Y) rising stem (or non-rising stem depending on specific model, such as bright stem support). It is designed with flanged connections for high-integrity pipeline installation. Constructed from stainless steel alloys like SS304 or SS316, it is primarily used to completely open or close the flow path within a pipeline system.

Available Configurations Include:

Non-Rising Stem Gate Valve (暗杆闸阀)
Rising Stem Gate Valve (明杆闸阀)
Vacuum Gate Valve (真空闸阀)
Jacketed/Insulation Gate Valve (保温闸阀)

Material Selection (Body & Bonnet)

The material choices ensure compatibility and durability in various corrosive and high-temperature environments:

CF8 (ASTM A351): Equivalent to SS 304 (General corrosion resistance).
CF3 (ASTM A351): Equivalent to SS 304L (Low carbon for improved weldability).
CF8M (ASTM A351): Equivalent to SS 316 (Enhanced corrosion resistance, especially against chlorides).
CF3M (ASTM A351): Equivalent to SS 316L (Low carbon 316 for severe corrosive/welded applications).
2520, 321, Duplex Stainless Steel (双向钢): For specialized, high-temperature, or high-strength/corrosion-resistant applications.

Applications

Stainless Steel Flanged Gate Valves are critical components used in the automatic control systems and piping infrastructure across diverse industries:

Chemical and Petrochemical
Power Generation (Steam lines)
Oil and Natural Gas
Pulp and Paper
Metallurgy
Marine and Shipbuilding

To select the correct stainless steel grade (e.g., CF8M/SS316) for your high-temperature steam or corrosive chemical application, please specify the working pressure and exact medium.
