TRI-SHARK

Share this article

Description.

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.
