A351-CF3M FLANGE END GLOBE VALVE 1500PSI SCREW RISING STEM STAINLESS STEEL GLOBE VALVE
Globe valves
A Globe valves is a linear motion valve and are primarily designed to stop, start and regulate flow. The disk of a Globe valve can be totally removed from the flowpath or it can completely close the flowpath.
Conventional Globe valves may be used for isolation and throttling services. Although these valves exhibit slightly higher pressure drops than straight=through valves (e.g., gate, plug, ball, etc.), they may be used where the pressure drop through the valve is not a controlling factor.

Body designs of Globe valves
There are three primary body designs for Globe valves, namely..
Tee Pattern or Z-body
Angle Pattern
Wye Pattern or Y-body body
Disk and Seat and Stem of Globe valves
Disk.. The most common disk designs for Globe valves are.. ball disk, composition disk and the plug disk. Ball disk design is used primarily in low pressure and low temperature systems. It is capable of throttling flow, but in principle it is applied to stop and start flow.
Composition disk design uses a hard, non-metallic insert ring on the disk, which ensures a tighter closure.
Plug disk design provides better throttling than ball or composition designs. They are available in many different designs and they are all long and tapered.
Seat.. Globe valve seats are either integrated or screwed in to the valve body. Many Globe valves have backseats inside the Bonnet. Back seats provides a seal between the stem and Bonnet and prevents system pressure from building against the valve pakking, when the valve is fully open. Back seats are often applied in Globe valves.
Stem.. Globe valves uses two methods for connecting the disk and the stem.. the T-slot and the disk nut construction. In the T-slot design, the disk slides over the stem, while in the disk nut design, the disk is screwed into the stem.
