and are manufactured from cast
and ductile iron, with stainless steel
discs. They can withstand operating
temperatures of between -20˚C
and +80˚C as standard, with higher
temperatures on request.
Polyurethane liner abrasion-
resistant butterfly valves – in a wafer
pattern or with a lugged design –
are used for on-off and control of
abrasive slurries. Butterfly valves
are available from BMG in standard
sizes between DN 50 and DN 400.
Locally-manufactured
KLEP
BMG diaphragm valves – between
DN 50 and DN 350, with manual or
pneumatic actuation – are designed
for abrasive slurry applications.
These flanged diaphragm valves
have a body pressure of PN 10
and can withstand temperatures
between -10°C and +80°C.
Long-lasting rubber and jumbo
rubber linings are suited for full-
bore diaphragm valves with a high
flow capacity and an efficient
sealing capability, which shuts off

slurry valves, which has been designed
to cope efficiently in harsh conditions,
includes robust butterfly and knife gate
valves, as well as diaphragm and pinch
valves.
any flow and prevents leakage. Full
bore diaphragm valves also have a
low pressure drop because there
is almost nothing obstructing the
flow of the fluid when the valve
is fully opened. This creates little
resistance to flow, which makes
these valves suitable for fluids with
abrasive particles.
Also included in the range are
unlined diaphragm valves, which
are suitable for water treatment and
general industrial applications.
FPV pinch valves–featuring a
design where the sleeve is pinched to
close mechanically or automatically
by means of hand-wheel or actuator
–are ideal for the control and
isolation of abrasive slurries.
Open frame pinch valves are
available from BMG with a short and
long frame design, in sizes between
DN 50 and DN 600.
The body is made from mild
steel, but stainless steel is also
available for specific applications.
These valves, with soft rubber
sleeves, have manual, hydraulic
and pneumatic actuation and can
withstand temperatures between
-20°C and +80°C.
BMG’s extensive range of
components for fluid technology
systems and general industrial
applications encompasses valves,
hydraulic hoses and fittings,
accumulators,
cylinders,
heat
exchangers, pneumatics, hydraulic
motors and hydraulic plumbing,
as well as pumps and reservoir
accessories.
The company also offers a
total process and lubrication
management solution to meet exact
market requirements.
BMG’s extensive range of industrial
slurry valves, which has been
designed to cope efficiently in harsh
conditions, includes robust butterfly
and knife gate valves, as well as
diaphragm and pinch valves.
“These industrial slurry valves
– which meet stringent quality and
safety specifications – are highly
efficient for the control and isolation
of abrasive slurries in many industries,
including power generation, chemical
and petrochemical, cement handling,
water treatment, mining and pulp
and paper,” says Willie Lamprecht,
national product manager, Valves,
BMG. “Failure of a valve and
subsequent leaking of corrosive
media can have devastating effects
on the safety of personnel and
equipment, leading to premature
system failure and costly downtime.
It is critical that the correct valve is
selected for every application, for
maximum safety, ongoing operation of
the plant and minimum unscheduled
maintenance.
“BMG’s highly-skilled team has
a thorough understanding of the
processes where valves are installed
and supports every component with
a dependable solutions service, to
ensure optimum safety, efficiency
and the extended service life of each
system. The selection of the correct
industrial slurry valve is based on
factors that include the size and shape
of particles, pressure, temperatures
and chemical content.”
Polyurethane-lined knife gate
valves are available from BMG in
standard sizes between DN 50 and
DN 600, with manual, pneumatic
and electric actuation. These knife
gate valves have a wafer pattern
