Design is highly
reliable O-ring seal,
not requiring any spring
in the operating
mechanism. Small bearing
surface of thrust washer
results in exceptionally
low torque operation
under full service
pressure.
Meets EN ISO 10297:2006
for working pressure up
to 200 Bar and CGA
V-9-2005 for Maximum
service pressure of 3000
psig, tested and
certified by BAM Berlin
and available with ''
mark as per EU directive
TPED 1999/36/EC.
Packing nut abutts at
the inner end with the
valve body to make metal
to metal seal. This puts
the packing nut into
compressive stress and
reduces risk of stress
corrosion cracking.
O-ring is provided in
the valve body for
secondary protection
against leakage past the
packing nut threads in
case of external impact
of cylinders.
In addition to the top
stem collar preventing
ejection of the stem,
the top stem and packing
nut are machined with a
step for additional
protection in the event
of shear cracking of the
collar/flange.
EPDM O-ring and high
durometer back up ring
provided on top stem
groove provides reliable
external tightness
around the stem.
The design does not use
any fluorinated polymers
in gas wetted duty with
toxic combustion
products. No “flaking”
observed with Nylon 66
thrust washer resulting
in excellent cycle life.
Valve body machined from
high tensile brass
offering greater
strength and wear
resistance. Stems
machined from tough and
wear resistant Naval
Brass.
As per Clause 4.3 of EN
ISO 10297:2006, wetted
parts including top stem
are not chrome plated,
thereby preventing
plating particles from
chipping off and
damaging threads,
seating surface and
seals.
For oxygen service CG-4
capsule design PRD for
Oxygen service as per
CGA S.1.1-2007 uses
Copper gasket for
permanent seal with
tamper proof T-30 Star
drive.
Valves with parallel
threads provided with
double O-ring
configuration in the
valve inlet.
Hytrel coated Brass
toggle designed to
minimize impact on
packing nut.
