An API 598 Globe Valve is a type of valve designed to adhere to the API 598 standard, which specifies inspection and testing requirements for various types of valves, including those with resilient-seated, nonmetallic-seated, and metal-to-metal-seated configurations. The operation of the API 598 Globe Valve involves the regulation of fluid flow by adjusting the position of the plug or disc element relative to the ring seat, allowing for precise control over the rate and volume of fluid passing through the valve.
