Applications

TB series ball valves are suitable for a wide variety of control and instrumentation applications. The trunnion ball and spring loaded seats enable them to perform in systems having dynamic pressure, flow, and temperature requirements. TB series valves are used in high-cycle low-temperature applications such as CNG fueling, and as isolation and switching valves in valve control panels and test stands. Their compact size makes them a good choice for panels and other applications where space is limited. End screw construction allows a wide variety of end connection size and type combinations.
