Warren Valve .5V852B-8THG - 1/2" Class 800 Forged Steel Globe Valve 

The Warren Valve .5V852B-8THG 1/2" Class 800 Globe Valve is a forged carbon steel flow control valve designed for high-pressure industrial and mechanical piping systems. As part of Warren’s 852 Series forged globe valve platform, it features a bolted bonnet and OS&Y (outside screw and yoke) rising stem design for dependable sealing, visible valve position, and long service life. Threaded or welded forged globe valves in this class are commonly built using ASTM A105N forged carbon steel bodies with graphite sealing components and stainless trim to support severe service and emissions-sensitive environments. These valves are widely used in oil & gas, process piping, steam, and high-pressure utility systems where precise throttling and reliable shutoff are required.
