Globe Valves - High Capacity, Cage-Guided Valve Bodies

This adaptation of the cage-guided bodies mentioned above was designed for noise applications such as high pressure gas reducing stations where sonic gas velocities are often encountered at the outlet of conventional valve bodies (figure 3-6). The design incorporates oversize end connections with a streamlined flow path and the ease of trim maintenance inherent with cage-style constructions. Use of noise abatement trim reduces overall noise levels by as much as 35 decibels. Also available in cageless versions with bolted seat ring, end connection sizes through 20-inch, Class 600, and versions for liquid service. Flow direction depends on the intended service and trim selection, with unbalanced constructions normally flowing up and balanced constructions normally flowing down.
