The MacoTango Electric Three-Piece Forged Trunnion Ball Valve uses a supported ball arrangement for automated shutoff.
The ball is supported rather than relying on the seats alone to locate it under pressure. The seat design, pressure load and stem friction still determine operating torque, especially at the maximum closing differential.
The supported-ball arrangement is combined with a forged three-piece body and electric operation. Seat construction and actuator torque should be selected at the most demanding pressure and temperature combination.
Consider this arrangement for larger sizes or higher differential-pressure isolation in compatible gas and liquid service. Pressure class, materials, seat construction and any cavity-pressure-management provision should be defined for the actual assembly.
| Ball support | Trunnion-mounted |
|---|---|
| Control function | On/off isolation |
| Valve motion | Quarter-turn |
| Seat selection | Duty-specific soft or metal seating |
| Actuation | Electric; supply and command interface selected for the assembly |
| Body construction | Forged; material grade selected for the service |
| Size and pressure class | Specified in the configuration datasheet for the selected model |
| Operating temperature | Limited by the complete material, seat, seal and actuator arrangement |
For a configuration-specific quotation, send the following information:
We will confirm the final configuration and datasheet against the stated duty before order acceptance.
No. Isolation functions depend on the seat arrangement and test basis. Specify the required function and verify it for the selected valve.
No. Seats, packing and other seals may limit the assembly before the body material does.
