The Cast Steel Globe Valve OS&Y Class 150 RF with hard faced seats is a heavy-duty flanged valve designed for reliable isolation and flow regulation in industrial, commercial, 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 commonly used 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 wear resistance and durability, making the valve suitable for more demanding services where seat life and sealing performance are important.
This valve features an outside screw and yoke design, with a stainless steel stem, graphite gaskets and packing, and ANSI B16.5 Class 150 raised face flanged connections. Face-to-face dimensions are in accordance with ANSI B16.10.
This valve is designed for high-pressure industrial environments, including refineries, petrochemical plants, power generation, and general process industries. It ensures reliable flow control and tight shutoff in demanding conditions.
The valve body is made from ASTM A216 WCB cast steel for superior mechanical strength and thermal resistance. Hard-faced seats provide excellent wear resistance, while the stainless steel stem ensures smooth, corrosion-resistant operation.
The Outside Screw & Yoke (OS&Y) design keeps the stem threads outside the process media, protecting them from corrosion and wear. It also provides a clear visual indication of valve position, improving safety and operational monitoring.
The valve has ANSI B16.5 Class 150 RF flanges and ANSI B16.10 face-to-face dimensions, ensuring secure connections and compatibility with standard pipeline systems. It is also API 600 / API 6D compliant.
Equipped with graphite gaskets and packing, hard-faced seats, and a durable stainless steel stem, this valve delivers tight sealing, long-term reliability, and smooth operation. Its design allows easy maintenance even under high-pressure and high-temperature service.
