Carbon Steel ANSI 300 Flanged Globe Valve with metal seat. Designed
and manufactured to BS 1873, Face to Face to ASME B16.10 with
flanges to ASME B16.5, Tested by EN 12266-1. Stainless Steel
reinforced graphite gasket and flexible graphite packing. 13CR
reinforced seats and disc for greater durability and wear. Great
for steam and high temperature applications. Globe Valves are also
regularly used over gate valves or other manual control valves
where the user wants to achieve a greater degree of flow control.
As the shaft comes down it has a 'globe shape' on the bottom of it
which slowly cuts down the flow before shutting off on the seat.
All globe valves come with cast heat numbers to give quality
assurance for testing and mil certificates.
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.
