Operating

Large handwheels for easy
operation.also avaliable
with gearing.motor actuators,
pneumatic or hydraulic actuators
for more difficult services.

Live Load Packing

In services requiring frequent cycling
or with high pressure/temperature
variations,live loading extends the service
life between maintenance periods
byrequiring less stments.Belleville
springs are employed to provide
constant packing gland stress.

OS&Y

Outside screw and yoke.Cast steel
gate valve yoke integral with bonnet
for 150Lb-8" 600Lb-6",
900Lb-4"&small.

bolted bonnet .welding bonnet and
pressure seal bonnet in services
requiring frequent cycling or with high
pressure/temperature variations.

End Connections

A choice of flanged ,RTJ flanged or
buttwelding end for piping flexibility.

Yokesleeve

Extra long thread engagement
between yoke sleeve and stem
provide long thread life.valves of
sizes larger than 150Lb-12",
300Lb-10",600Lb-6",
900Lb/1500Lb/2500Lb-4"
are regularly provided with roll
bearing yokes.

Lantern Ring And Double Packing Set

lantern ring leak-off fitting connection
and double packing stack is
optionally avaliable for critical
services.

Body-to-Bonnet Joint

A flat face gasket joint is used in the
150lb valves. A male and female joint
is used in 300lb to 600lb valves.ring
joint is used in the body to bonnet
connections in 900lb & higher
rated valves.

Stem

All wedge gate valves are provided
with upset forged T-head stems.
By forging the T-head ,the stem at
the stem-wedge connection is
stregthened,this design also allows
the wedge possibility of a bent
stem jamming the wedge.

Wedge

Integral guide rib faces assure
self-centering of wedge.flexible
wedge gate valve has a one-
piece,twin-disc wedge,which is
designed so that each half flexes
independently.avaliable in solid,
flex split and his designs.
