“T”- Pattern Globe Valves
Globe valves are used for flow regulation, frequent operation, increased flow
resistance or for positive shut off when closed. Globe valves are closing-down
valves in which the closure member is moved squarely on and off the seat. By
this mode of disc travel, the seat opening varies in direct proportion to the travel
of the disc. This proportional relationship between valve opening and disc travel
is ideally suited for duties involving regulation of flow rate. Globe valves can also
be used for on-off duty, the seating load can be positively controlled with high
sealing capacity.
The change in direction of fluid flow through these valves produces increased
resistance and pressure drop. The standard Straight “T”-Pattern valve body
is the most common, but because of its tortuous flow passage it offers the
highest resistance to flow of the patterns available. Globe valves are used in
many industrial applications including the oil and gas industry, pharmaceutical,
manufacturing, automotive, and marine. Globe valves are also recommended for
services requiring frequent operation and positive shut off.
