ANSI Cast Steel Globe Valve Descriptions
ANSI cast steel globe valve is also called stop valve, which is one type of the most important shut-off valves. Globe valve is open or close by bringing pressure to the valve stem, and the stem bring pressure to the valve disc, achieving the sealing surface to be without leakage by force. There are straight type globe valve, angle type globe valve and plunger type globe valve. And globe valves can be with flanged ends, threaded ends and welded ends. ANSI globe valves are widely used in series of industries, especially in oil & gas filed, power plant, etc. Just feel free to contact us now to get best prices. 30 years of experience. High quality. Big stock. Fast delivery.

- Oil & Gas
Large handwheels for
easy operation. Also
available with gearing.
motor actuators,
pneumatic or hydraulic
actuators for
more difficult services.
2 LIVE Load Packing
In services requiring
frequent cycling or with high
pressure/temperature
variations, live loading
estends the service life
between maintenance periods
by requiring less frequent
packing gland adjustments.
Belleville springs are
employed to privide constant
packing gland stress.
3 OS & Y
Outside Screw and Yoke.
Cast steel gl obe valve yoke
integral with bonnet for 10&
and smaller.
4 BB
Bolted bonnet. Welding
bonnet and pressure
seal bonnet inservices
requiring frequent cycling
or with high pressure/
temperature variations.
5 End Connections
End Connections
A choice of Flanged,
RFJ flanged of Buttwelding
end for piping flexibility.
6 Yokesleeve
Fumished in aluminum
bronze to reduce
operating torque, Most
sizes fumished with ball
bearing yokesleeves.
7 Lantern ring and
double packing set
Lantem ring with leak-off
fitting connection and double
packing stack is optionally
available for critical services.
8 Body-to-Bonnet Joint
A Male and Female joint
or Tongue and Groove
joint is used 150Lb to
600Lb valves. Ring joint is
used in the body to bonnet
connection in900Lb&
higher rated valves.
9Disc
Plug disc is stom guided on allsizes. Disc has a differential angle
front the seat to provide a line
contact for maximum sealing.
The bottom of V-port disc is
fuided by the body seat
ring for maximum disc stability
in throttling applications. The
soft TEFL ON ring is excellent
for lower temperature service
where tight shutoff is required.
10 Seat Rings
Separate heavy duty, full
ported rings for easy
maintenance. Screwed or
welded connection into
body.
