The structural forms of the internal thread globe valve body are straight-through type, direct-current type and right-angle type. The straight-through type is the most common structure, but it has the greatest resistance to the fluid. The direct-flow fluid resistance is small, and it is mostly used for fluids containing solid particles or high viscosity. The right-angle valve body is mostly forged, which is suitable for the globe valve with smaller passage and higher pressure.
