Forged Steel Cryogenic Globe Valve product description
Forged Steel Cryogenic Globe valves(Generally flanged connection,
but butt-welding is optional) are suitable for use on various kinds
of pipeline from Class150 To Class900, PN16 To PN100 to cut off or
connect the flowing of medium. By using different material, the
valves could be suitable for medium such as water, steam, oil,
nitric acid, acetic acid, oxidizing substance, carbamide and etc.
Manual/bevel gear/pneumatic or electric actuators could be chosen
by needs.

| |
| Application fields | For application in fields such as electric power industry,
petroleum refining, petrochemical engineering, offshore oil, tap
water engineering in urban construction, chemical engineering, etc. |
| Other remarks | The extension dimensions of valve stem and bonnet may vary
according to different temperature ratings. |
| Other remarks 2 | As valves subject to a temperature ≤-101℃ shall be protected
against subzero deformation, the main parts are subzero treated. |
| Other remarks 3 | The sealing faces of valve seat and valve clack are build-up welded
with hard alloy to improve the erosion resistance and extend the
service life of valve. |
| Other remarks 4 | The friction between sealing faces is smaller during opening and
closing, facilitating a longer service life. |
| Other remarks 5 | The valve clack is of taper, needle, ball and parabola types, and
can be used to adjust the flow rate. |
| Other remarks 6 | SS+ graphite or metallic seal or pressure self-sealing is adopted
between valve body and bonnet for reliable sealing. |
| Other remarks 7 | Rising stem structure, making the valve switch position be clear at
a glance |
| Other remarks 8 | The valve stem thread will not come into contact with the medium,
so the corrosion of medium to the thread is reduced. |
| Other remarks 9 | Small switching moment, reliable sealing |
| Other remarks 10 | The valve clack can be machined into parabola, spherical, needle
shapes, etc. according to the requirement of customer. It can be
used for adjustment (rough adjustment) on pipeline. |
| Other remarks 11 | Short stroke is suitable for application at positions subject to
frequent opening. |
| Other remarks 12 | Y-shape stop valve – the streamline flow pass has a very high flow
coefficient, and can maximally reduce the pressure drop through the
system. |
| Other remarks 13 | Through improving the structural design and selecting reasonable
packing structure and qualified packing supplier, the valves can
meet the Class A sealing test requirements of ISO 15848 FE. |
