The Cast Steel Globe Valve OS&Y Class 300 RF 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 A216 WCB cast steel, it provides strong mechanical performance and dependable service in suitable pipeline systems.
The globe valve design is suitable for applications where controlled flow regulation or throttling is required, offering more gradual flow adjustment compared with standard on/off isolation valves. The hard faced seats provide improved durability and wear resistance, making this valve suitable for demanding services where long-term sealing performance is important.
This valve features an outside screw and yoke design, with a stainless steel stem, graphite gaskets and packing, and ANSI B16.5 Class 300 raised face flanged connections. Face-to-face dimensions are in accordance with ANSI B16.10, with design and manufacture to API 600 or API 6D.
This valve is ideal for high-pressure industrial systems, including oil & gas, petrochemical, power generation, and general process industries. It ensures reliable flow control and tight shutoff under demanding conditions.
The valve body is made from ASTM A216 WCB cast steel, providing excellent mechanical strength and thermal resistance. Hard-faced seats increase wear resistance, and the stainless steel stem ensures smooth, corrosion-resistant operation.
The Outside Screw & Yoke (OS&Y) design keeps stem threads outside the process media, preventing corrosion and wear. It also provides a clear visual indication of valve position, improving safety and operational control.
The valve features ANSI B16.5 Class 300 RF flanges and face-to-face dimensions per ANSI B16.10, ensuring easy installation, secure connections, and compatibility with standard pipeline systems.
Equipped with graphite gaskets and packing and hard-faced seats, the valve provides tight sealing, thermal stability, and long-term reliability. Its design allows smooth operation and simplified maintenance, even in high-pressure, high-temperature service.
