WZK two-channel
diverter valve
The two-way WZK diverter valve
is the right solution for very fne
and abrasive products and as a
collection valve. The pipe inserts
are available in different wear pro-
tection options such as hardened
pipes or tungsten carbide welded
inserts, in order to provide the
right protection for different bulk
materials, based on product hard-
ness and conveying pressures.
CONCLUSION
Intensive research and experience
have shown that abrasive bulk ma-
terials can cause signifcant wear in
equipment in pneumatic conveying
systems for the minerals industry.
In order to ensure proper function
of components such as rotary and
diverter valves under these condi-
tions, specialized wear protection
options are necessary. This wear
protection concept allows rotary
valves to be an energy-effcient
and low maintenance alternative
solution for the cement industry.
