These valves provide a very cost effective alternative
to the more expensive valves manufactured in exotic
materials such as Hastalloy, Titanium etc. Available
with a one piece ball and stem or alternatively a floating
ball with blow out proof stem. Ball available in Aluminium
Oxide for abrasive applications. One piece PTFE bellows
type packing is pre loaded using a Stainless Steel spring
gland follower and ensures no leakage to atmosphere
even during hot and cold cycling. Valves are designed
with optimum lining thickness to ensure permeating media
such as Chlorine does not come into contact with the
body. All Richter products are finished externally with
a high quality epoxy paint.
Features and Benefits:
Thick liner 100% inspected at 20,000
VDC for defects is made from highly corrosion resistant
FEP to 300°F (150°C) or PFA to 400°F (200°C).
Available with equal percentage

Blow out proof stem
Double stuffing box for applications requiring absolute
safety
Tight Shut Off
Liners are anchored and suitable
for use on vacuum applications
Size Range: 25-100mm
Operating Range: -60°C - 200°C
Body Material: S G Iron
Lining Material: Mg-PSZ
End Connections: Flanged BS4504 Table 10,150LB
Recommended when nothing else will work in abrasive
slurries, high temperature corrosives and services with
large temperature fluctuations.
All interior body surfaces and the ball are made of
solid Mg-PSZ for superior erosion/corrosion resistance.
Excellent strength and thermal shock resistance. A wide
selection of stem material options available 316 stainless
steel, Hastelloy C-276 or Mg-PSZ (Partially Stabilized
Zirconia) ceramic.
Full port minimizes pressure loss and increases flow
capacity to reduce energy and pumping costs.
Features and Benefits:
Class IV shutoff, Per FCI 70.2
ISO 5211 mounting pad makes actuator mounting quick
and easy.
PTFE chevron or graphite packingrings in the deep
stuffing box protects against external leakage to
the atmosphere.
Optional V-port ball provides equal percentage control
for throttling abrasive/corrosive media.
Minimum cavity space minimizes the retention of
line media within the body cavity so product contamination
problems are significantly reduced.
AKH7-KP valves are easy to install
in glass pipe systems with socket/ball or plane ends
according to DIN/ISO 3587 and 4704.
Long-term protection against atmospheric
leakage is provided by PTFE chevron packing rings in
the deep stuffing box and by the molded liner/seal.
Molded fluorocarbon resin liners are
made of either FEP or PFA, depending upon application,
for both long service and high corrosion resistance
due to their uniform thickness. The liners' non-stick
properties are also ideal for handling highly viscous
fluids or for those process applications with high purity
requirements
Features and Benefits:
For flange/glass end connections
the AKH7-KPF is available.
AKH7 valves are also available
with conductive material for the linings, seals and
gland packings.
Anti-static device protects against
potentially dangerous electrostatic discharges.
Stem is internally assembled to
eliminate possibility of blowout.

Unique, energized seat design
results in bubble tight shutoff. The spherical ball
and socket disc/ liner design provides a 360 degree
contact seat seal. The rounded radius of the disc fits
into the socket of the machined liner and stays in constant
contact with the seat. The liner itself is recessed
into the valve body for added stability and to prevent
possible leakage due to cold flow or improper valve
installation. A live loaded elastomer seat energizer
enhances sealing. Isolated and protected in the grooved
valve body, the elastomer energizer operates independently
of mating flange torque for constant line seal performance.
Features and Benefits:
1/8 in (3 mm) thick (nominal) rigid
machined PTFE or UHMWPE liner is recessed in body
preventing cold flow and facilitating installation.
Disc swing is compatible with ASTM
F423-82 fluoropolymer lined pipe
ASTM A395 ductile cast iron split
body provides Popular Double-D shaft drive provides
positive valve position indication and simplifies
adaption to automatic operation.
Tight Shut Off
Interchangeable actuator mounting
plate accommodates ISO, MSS or special actuators.
10-position locking lever and throttle plate or gear
operated options are available.
Epoxy coated body and mounting
plate resist the effect of atmospheric corrosion
A key design feature of T-41 and T-43
valves is the thick, one-piece continuous PTFE lining
that covers all wetted surfaces in the body. Since the
body is unwetted, the standard material is economical
Ductile Iron. We offer optional stainless bodies for
corrosive environments. The plug is PFA-Encapsulated
and the PFA covering extends up the stem through the
top cap. A sealing surface as much as 10x greater than
other lined valves assures drop tight shut-off. In addition
to the large sealing area,sealing is omnidirectional
and is totally independent of line pressure.
The primary seal to the atmosphere
is between the plug and the seal band at the top of
the liner. As a secondary seal, a dynamic self-adjusting,
self-energized, reverse-lip PFA diaphragm seal prevents
stem leakage. If line pressure should force liquid to
the stem seal area, the self-energizing reverse lip
PFA diaphragm will be forced against the stem to prevent
external leakage.
Never replace valve seats. Simply
reseat the plug with a quick and easy in-line adjustment.
An open-end wrench and a few seconds are the extent
of your maintenance requirements.
