T
he company’s expansion programme in this sector
also involves increasing stockholdings through more
than 140 BMG branches and a wide distribution
network in South Africa and across borders into Swaziland,
Zambia, Botswana, Mozambique, Namibia and Tanzania.
“BMG has boosted its fluid technology services with
dependable technical support to ensure optimum safety,
efficiency and extended service life of every system, even in
corrosive environments. With broad technical capabilities,
the team is able to solve problems, in applications where
conventional components have failed after short periods of
service,” explainedWayne Holton, fluid technology manager,
BMG – Bearing Man Group.
“BMG’s fluid technology services also cover project engi-
neering and consulting, cylinder design and manufacture,
training, repair and testing and onsite container services.”
Butterfly valves are important
The company’s extensive range of components for fluid
technology systems and general industrial applications,
includes valves, hydraulic hoses and fittings, accumulators,
cylinders, heat exchangers, hydraulic motors and hydraulic
plumbing, as well as pumps and reservoir accessories.
“Compact butterfly valves, with good flow characteristics
and low maintenance requirements, are important compo-
nents in BMG’s extensive range of valves for industrial flow
control,” Willie Lamprecht, national product manager valves,
BMG, told
ChemTech
. “An advantage of using quarter turn
butterfly valves rather than any other type of valve, is the
simple, wafer-shaped design, with fewer parts, for easy
repair and minimal maintenance,” he continued.
“Although butterfly valves and ball valves are both
quarter turn, the benefit of butterfly valves is when they are
actuated pneumatically, they open and close very quickly.
The rotational disc in butterfly valves is lighter than a ball
and these valves requires less structural support than a
ball valve of the same diameter.
“Unlike a ball valve, the disc of butterfly valves is always
present in the passageway within the flow. This means
a pressure drop is induced in the flow, regardless of the
position of the valve. Ball valves should only be used for
isolation, whereas butterfly valves can be safely used for
isolation and control of flow.”
BMG’s Desponia centric butterfly valves (DN 25 -1600)
with an elastomer liner, are designed for safe and reliable
regulation of liquids and gases in diverse industries. This
range has a maximum working pressure of 16 bar and
an operating temperature range of between -20 °C and
+140 °C, according to the material.
Bianca centric butterfly valves (DN 32 -900) with an
on/off and control service, have a durable plastomer liner
suitable for aggressive and corrosive fluids. These high per-
formance valves have a 16 bar maximum working pressure
and an operating temperature range of between -20 °C and
+200 °C depending on working conditions.
