TB and TBH Trunnion Design
The TB and TBH Series use a trunnion-style ball configuration designed for high-pressure fluid-control applications.
The fixed-ball arrangement incorporates seat sealing on both sides of the ball. The three-way configuration provides three connected valve ports for manual flow-path switching according to the required system arrangement.
Double-Ferrule Tube Connections
This configuration uses double-ferrule tube connections at all three valve ports.
Fractional tube sizes are available from 1/4 in. to 1/2 in., while metric tube sizes are available from 6 mm to 12 mm.
The required tube outside diameter and tubing material should be specified when selecting the valve.
Pressure and Temperature
TB Series configurations have a maximum working pressure up to 6000 psig (414 bar), while TBH Series configurations have a maximum working pressure up to 10,000 psig (689 bar).
The working temperature range is 0°F to 450°F (-18°C to 232°C).
Applicable working pressure depends on the selected series, operating temperature, sealing materials, tube connection, and service conditions. Final valve selection should be based on the actual system requirements.
Three-Way Flow Configuration
The three-way configuration is designed for applications requiring manual switching between connected fluid lines.
The required flow-path arrangement should be specified when selecting the valve so that the appropriate three-way configuration can be confirmed for the application.
Typical Applications
TB and TBH trunnion ball valves are suitable for high-pressure systems requiring manual flow-path switching, including process instrumentation, test systems, hydraulic systems, and equipment fluid lines.
Application suitability should be confirmed according to the required pressure, temperature, process fluid, tubing specifications, flow-path requirements, and material compatibility.
Selecting the Right Configuration
When specifying a double-ferrule three-way trunnion ball valve, provide the required tube outside diameter, tubing material, operating pressure, temperature, process fluid, flow-path requirements, and quantity.
The required working pressure is particularly important when selecting between the TB and TBH Series.
