No. 140 Series Valves provide long
trouble-free service at economical
cost. Their design incorporates such
quality features as stainless steel
stems and ballchecks. A comprehensive
selection of connections provides
the versatility required to conform
to most piping requirements. Optional
features permit a high degree of
customization to meet very specific
demands.
Choices of Models:
Safety Shut-off: All No. 140 Series
Valves are equipped with stainless steel ballchecks upstream
from the seats which instantaneously shut off flow of medium
being gaged in case of gage glass breakage. The ball may be
omitted on request. Bonnet: The bonnet on all No. 140 Series
Valves screws directly onto the outside of the forged body.
The inner area bears on the packing gland.
Union Tank Connection: Series 140 Valves
are equipped with union tank connections which permit simple
installation and easy access to the ballcheck.
Union Gage Connection: No. 147 and
No. 144 are furnished with a union gage connection which allows
a top and bottom connected gage to be turned to any desired
angle for convenient visibility. It also makes possible removal
of the gage without removing the valves or draining the liquid
from the vessel - a feature which saves time when the gages
must be cleaned or maintained.
Offset Patten: No.146 and No.147 valve
bodies are designed so that the gage connections are offset
7/8" from the centerline of the vessel connections. By
removing the plug, the interior of top and bottom connected
gage may also be swabbed without disassembly. |

| MATERIALS |
| No. 140 Series Valves have steel bodies and malleable iron handwheels. Long life is assured by the use of stainless steel for the stem, and ballcheck. Materials used to conform to or exceed requirements of A.I.S.I., A.S.TM. and/or A.P.I. - A.S.M.E. for recommended pressures. |
| |
| SPECIAL CONNECTIONS (extra charge) |
No. 140 Series Valves can be furnished upon
request with Flanged, Socket
Welding, Solid
Shank (non-union) and Spherical Union Connections. The use of Spherical Unions
on inlets and outlets with top and bottom connected gages
is particularly valuable lest the vessel connections are
not perfectly parallel. This construction will compensate
for up to 10° misalignment of vessel tapping in any direction
from the stem axis and up to plus or minus variation from
mean centers. The same compensation may be had on side connected
gages using single spherical tailpieces on the outlet connections. |

| ROUGHING DIMENSIONS |
| To determine maximum space available
for top and bottom connected gage, deduct from center to center
dimensions: |
| 3½" on Nos. 143 and 146 |
| 5-7/8" on Nos. 144 and 147 |
|
Note A. ¾" dimension applies to all ½" N.P.T.
end connected Reflex and Transparent
gages except L-10 which is 1¼".
Note B. To determine overall length of ½" I.P.S.
nipples add 7/8" to distance between gage and valve. For
side connected gages: Refer to bulletin on page selected. Using
No. 143 or 144 valves the side centers on the gage and the
centers are the same. Using No. 146 or No. 147 valves with
offsets inside gage centers, deduct 1¾" from side centers.
Using No. 146 or No. 147 valves with offsets outside gage centers,
add 1¾" from side centers. |

| SPECIAL FEATURES |
Vertical Rising Ballcheck: No. 147. An additional safety feature in the bottom valve of a top and bottom connected assembly is an optional vertical rising ballcheck on the downstream side of the seat. This arrangement shuts off the flow of liquid in case of fracture of the instrument or connecting piping and eliminates the horizontal ball in the bottom fitting. A ½" male drain is standard. A cap may be furnished on request.
Bleed Fitting: A bleed fitting is available making it possible to bleed pressure from the valve and connected instrument without breaking any threaded connections. The bleed fitting is designed so its stem cannot be withdrawn accidentally. It is tapped for 1/8" N.P.T. discharge. |
