Valbart designed the Trunnion Mounted Control Ball Valve (TMCBV) to operate at high pressures while minimizing the torque needed to operate the valve. The spring-loaded, process energized seats offer tight (Class IV and Class V) shutoff at any pressure. In most cases, the TMCBV’s capacity is greater than that of a comparable globe valve. This allows the customer to use a smaller, lighter valve and experience cascading savings. This valve also requires a smaller, less expensive actuator and less expensive pipe supports.

Features & Benefits
- Wide range of trim designs based on industry-proven technologies such as MegaStream, CavControl and Z-trim
- Metal to metal, tungsten carbide-coated seats provide ANSI FCI 70-2 class V shutoff up to Class 2500 and API 10000
- Accurate machining of stem and bonnet sealing surfaces ensures compliance with the most severe pollution control regulations
- Geometry allows easier overlay of special alloys on wetted parts including body, seat, ball and seat pockets
- Very tight tolerances maintained in stem-to-ball and stem-to-actuator connections
- Higher flow capacity for a given size results in a smaller size valve and actuator, thus leading to significant space, weight and cost savings
