Precision Control for Demanding Industrial Processes
TRI-SHARK High-Performance Control Valves deliver precise flow regulation in applications where reliability, tight shutoff, and long service life are critical. Designed with a rugged triple-offset butterfly valve geometry, these valves combine accurate throttling capability with exceptional sealing performance even under challenging process conditions.
Unlike traditional control valves that rely on soft seats or complex trim assemblies, TRI-SHARK valves utilize a robust metal-seated design that resists wear, erosion, and high temperatures. This makes them ideal for industries where process stability, minimal maintenance, and consistent control accuracy are essential.

Q & A
TRI-SHARK High-Performance Control Valves Q & A
TRI-SHARK control valves use a triple-offset butterfly valve design rather than a conventional globe valve structure. This design reduces friction between sealing surfaces, which improves durability and minimizes wear during throttling. As a result, TRI-SHARK valves often provide longer service life, lower maintenance requirements, and excellent shutoff performance while still delivering accurate flow control.
TRI-SHARK valves are ideal for demanding industrial processes such as steam control, power generation, refining, petrochemical processing, and chemical manufacturing. They perform particularly well in applications involving high temperatures, high pressures, or abrasive media where traditional control valves may wear quickly.
Yes. One of the key advantages of TRI-SHARK valves is their ability to combine accurate modulating control with reliable shutoff. The advanced metal-seated sealing system allows the valve to regulate flow smoothly while still achieving tight sealing when closed.
TRI-SHARK valves can be equipped with pneumatic, electric, or hydraulic actuators depending on the application requirements. They are also compatible with modern digital positioners and process control systems, enabling precise automated control in industrial environments.
The triple-offset design minimizes friction and wear between sealing surfaces during operation. Combined with durable metal seating materials, this reduces the frequency of maintenance and replacement parts, lowering the total lifecycle cost compared to conventional control valves.
