Zwick – Tri-Shark Control ValvesEnquire Now
The Zwick Tri-Shark Control Valve is a patented solution, which combined the Tri-Con Triple Offset Valve with our throttling cartridge to form the Tri-Shark. With this combination it is possible to control the flow even at angles of less than 25°. The ratio is 1:100 in comparison to an ordinary globe valve with a ratio of only 1:30.
Globe valves can be only used in single direction and are limited for shut off applications due to their lower leakage classes. On the opposite, our Tri-Shark solution can be used in both flow directions and with Zero Leakage shut off! The Body design includes a reduced trim, either one or two sizes down from the ordinary pipe diameter, means that the client not only safes the cost for the shut off valve next to his control valve, but also no more pipe reduction or modification is required, that’s the reason why the Tri-Shark control and shut off valve can be installed in the smallest spaces; no matter if in high or low pressure applications or made out of nearly any metallic material grades.
Another great advantage of the Tri-Shark valve is that due to the reduced trim, the actuator size is by far smaller and of course cheaper. Ideal applications are severe and overcritical services, Skids, filling or loading stations, geothermal steam, technical gases ,etc. They are suitable for a wide range of services, from -196°C up to +815°C, including liquids, gases and steam.
