The TRI-SHARK series is a patented solution consisting of a
combination of the Shut-off valve TRI-CON and a regulation
cartridge, called SHARKTOOTH. It combines the advantages of
our metal seated, triple offset TRI-CON series with the features
of a control valve.³ Therefore, it is still possible to regulate
precisely even if the opening angle is very small.
Due to the sandwich construction of the TRI-SHARK series it
is useable for narrow face-to-face dimensions where standard
stroke valves cannot be used anymore. Due, to the compact
construction and the already highlighted technical properties a
wide field of applications can be served optimally (e.g. SKIDS,
industrial gas, filling- and charging stations, geothermal
steam etc.)
The TRI-SHARK series minimizes emerging cavitation due to
its design, if it is used for liquid media. For gaseous or vaporous
media a reduction of the noise level is achievable. The dynamic
torques are reduced significantly compared to standard shut-
off valves which allows the possibility of using smaller and
therefore cost-saving actuators.
Due, to the triple offset design and to the metal
sealing a premium sealing solution can be achieved,
depending on the given application.³ Furthermore, our
TRI-SHARK series is bi-directional applicable – a preferred
flow direction like stroke valves imply does not exist. The
TRI-SHARK series has an almost equal percentage inherent
characteristic. Depending on the design a control rage of 100:1
is achievable. Conventional control valves feature a control rage
of 50:1 in standard design. Therefore, our TRI-SHARK series
offers a greater range compared to an ordinary control valve.
Based on the previously shown features, the TRI-SHARK
series offers great advantages in a wide range of applications.
