Actuators
A valve actuator is the mechanism used to open and close a valve. It can be operated manually through the use of a gear, wheel, or lever; however, actuators that require more force often use hydraulic, pneumatic, or electrical power. Actuators can be automated for industrial settings, which is also more efficient and allows remote operation. All actuators from TVI are mounted and tested to ensure optimal operation. Our heavy-duty designs ensure reliable operation and long-term stability.
Stem Extensions
Valves are controlled through manipulation of valve stems, and a valve stem extension allows for buried valves to operate above ground level. This creates simple access to the valve without having to implement a more arduous solution such as valve pits, man holes, and other alternatives.
Manual Gears
Manual valves are often used to regulate the flow of liquid or gas within a system. In a gear-operated valve, a manually operated wheel or lever is connected to a gear. When the gear turns, it moves a valve disc, which controls the fluid flow. Manual gear valves offer a high level of control and accuracy. Our durable design is made of corrosion-resistant materials that can withstand a broad range of temperatures.
Threaded Lugs
Lug-style butterfly valves used in dead-end service generally have a reduced pressure rating. Lug-style valves are unique because both sides of the valve’s body have threaded inserts – which can be adapted for all types of liquid and constraint.

Locking Devices
Valve locking devices include butterfly valves, ball valves, and sluice valves. They prevent valves from opening during system repairs and maintenance, which helps to ensure worker safety. TVI’s valve locking devices incorporate durable, corrosion-resistant designs with an easy-to-use color display. We make our devices easy to install to reduce overhead and keep your operation running smoothly.
Valve Flanges
Valve flanges use bolts, gaskets, and other connectors to seal pipes, valves, and other fluid system components together. Although they may be welded together, removable flange hardware allows for easy maintenance, repair, cleaning, and inspection. TVI offers a wide range of corrosion- and temperature-resistant valve flanges with an exceptionally high degree of design accuracy and durability.
Valve Fasteners
Valve fasteners are the hardware used to connect components at joints in a fluid system. Common valve fasteners include screws, nuts and bolts, and wing nuts. TVI provides a range of valve fasteners in a variety of materials, including metal alloys, PVC, PP, and PVDF. Our valve cover fasteners are easy to use and inexpensive, with a compact, sturdy design and long service life.
