TRI-SHARK Control Valves
TRI-SHARK control valves are able to achieve a nearly equal percentage inherent characteristic which greatly extends the control rangeability. Furthermore they offer great advantages in the field of cavitation reduction and noise attenuation, as well as in dynamic torque reduction.
They are suitable for a wide range of services, from cryogenic temperatures till -196°C up to +815°C, including liquids, gases and steam.

EXCEPTIONAL PERFORMANCE, SIMPLICITY, AND ECONOMY!
Reduces Aerodynamic Noise Up to 15 dBA
As the vane turns within the Sharktooth Throttling Trim Cartridge, multiple, optimized, throttling slots are
gradually exposed to flow. Then, at higher flows, when the vane has cleared the contoured slotted portion of the
control cartridge, the resultant lower pressure drop will alleviate any further noise problems.
Anti-Cavitation Properties
TRI-SHARKs twenty-five percent higher incipient cavitation index allows for higher pressure drops than
ordinary butterfly valves, while exhibiting much less noise, cavitation, and damage. Even if cavitation does occur in higher pressure drop situations, the shorter vapor jets produced by the slots will avoid the damaging effects caused by large vapor jets, referred to as “super cavitation”
More Control with Less Torque
TRI-SHARKs dynamic torque requirements are 60 percent less than ordinary butterfly valves, even at high-end Cv’s, thereby providing exceptional stability throughout its control range. TRI-SHARKs Triple Eccentric Metal-to-Metal Seating requires lower breakaway torques than either butterfly or rotary plug control valves and, its extended torque reversal point allows for an expanded range of control.
Excellent Control Range
TRI-SHARK Control Valves have an effective control range that extends from 1 percent at 5 degrees of travel to 100 percent at 90 degrees of travel. Its equal percentage flow characteristic fits the vast majority of control loop requirements
ZWICK & Sharktooth – Control Valves are Ideal for Most Applications
By combining the Sharktooth Throttling Control Cartridge with our Triple Eccentric Butterfly Valves, just one style of valve can be used for both on-off, and control applications. It’s the smart choice for today’s control systems engineer.
