The Stainless Steel Globe Valve OS&Y Class 300 with hard faced seats is a heavy-duty flanged valve designed for reliable isolation and flow regulation in demanding industrial and process applications. Manufactured from ASTM A351 CF8M stainless steel, it provides excellent corrosion resistance and dependable performance across a wide range of compatible media.
The globe valve design is suitable for applications where controlled flow regulation or throttling is required. The hard faced seats provide improved wear resistance and durability, making this valve suitable for more demanding services where long-term sealing performance is important.
This valve features an outside screw and yoke design, a stainless steel stem, and graphite gaskets and packing for high-integrity sealing. It is supplied with ANSI B16.5 Class 300 flanged connections, with face-to-face dimensions in accordance with ANSI B16.10. Design and manufacture are to API 600 or API 6D.
Smaller sizes from 1″ to 8″ are handwheel operated, while larger sizes from 10″ and above are supplied with gear operation for easier manual control.
This valve is ideal for oil & gas, chemical processing, power generation, and general industrial systems. Its CF8M stainless steel body and hard-faced seats provide excellent resistance to corrosion, high pressure, and high temperatures, making it suitable for harsh and demanding environments.
The body is made of ASTM A351 CF8M stainless steel, offering outstanding corrosion resistance and mechanical strength. Hard-faced seats extend service life and maintain tight sealing even under high-pressure, high-temperature, or abrasive conditions. The stainless steel stem ensures smooth operation and long-term reliability.
The Outside Screw & Yoke (OS&Y) design keeps stem threads external to the process media, reducing wear and corrosion. It provides a clear visual indication of valve position, simplifying monitoring and control. The rising stem enables precise throttling and smooth valve operation.
Yes. The valve features ANSI B16.5 Class 300 flanged ends and ANSI B16.10 face-to-face dimensions, ensuring easy installation in standard industrial piping systems. This makes it straightforward to integrate, replace, or upgrade existing valves.
For sizes 1" to 8", the valve is handwheel-operated for simple manual control. Sizes 10" and above come with gear operation for easier handling in larger pipelines. This flexibility allows precise control in a variety of industrial installations.
