Globe valves are used primarily for throttling, regulation, and flow control, characterized by a spherical body where the fluid path changes direction, increasing pressure drop. Design and wall thickness for cast body valves are governed by API 623, while forged small bore valves adhere to API 602. Pressure-temperature ratings and end connections follow ASME B16.34. Inspection and testing focus on smooth linear movement and seal integrity, following API 598. Required tests include hydrostatic shell and high-pressure seat leakage tests. The integrity of the backseat, which allows for packing replacement under line pressure, is verified through a dedicated test.
