Parts Number Legend
|
| 1 | Hand Wheel: Steel or Nodular Iron
handwheels are well shaped and large
enough to give ease of movement when
operating the valve, even under maximum
differential pressure. |
| 2 | Yoke Sleeve: Cast aluminum, bornze,
stainless steel or ductile iron having high
resistance to wear and a high melting
point. |
| 3 | Gland and Flange: Normally supplied in
two pieces, either forged or cast stainless /
carbon steel. |
| 4 | Gland Bolts and Nuts: Are of the eyebolt
type which can be swung outward for
ease of gland repacking. |
| 5 | Bonnet Bolting: Studs and nuts are
manufactured from alloy steel to the
relevant ASTM standards |
| 6 | Body: Basic dimensions, i.e. wall
thickness, face to face and flanges comply
with the relevant API, ANSI, BS
standards. |
| 7 | Bonnet: It is machined to accept the yoke
sleeve and incorporates a stuffing box
dimensioned with the relevant standards. |
| 8 | Back Seat: Provides seal with stem when
full open, typically integral with overlay or
solid trim material. |
| 9 | Stem: Provides vertical movement of
wedge either rising, non-rotating or
rotating, non-rising. |
| 10 | Disc: Normally supplied of the flat,
tapered, or plug type, or on request, of the
parabolic regulating type, always free to
rotate on the stem. Special attention is
give to the seating face which is ground
and lapped for a perfectly tight seal. |
| 11 | Seat Rings: Finished surface provides seal
with disc. Installed by threading, seal
welding, pressing, or as integral part of
body. |
