TCB Series™ & FCB Series™ V-Port Control Ball Valves
Available In: AL, AR, LA, MS, TN
The S&S® TCB Series™ and FCB Series™ V-Port Control Ball Valves are engineered for precise throttling control in applications where high capacity, tight shutoff, and mechanical durability are required. These valves are well suited for both general and severe service control, delivering stable performance across a wide range of pressures, temperatures, and process conditions.
Commonly installed in chemical, petrochemical, refining, power generation, oil and gas, aerospace, and decarbonization applications, the TCB1 and FCB1 platforms combine the flow efficiency of a ball valve with the controllability expected from a true control valve.
Unlike conventional on/off ball valves, the TCB1 and FCB1 Series use precision-machined V-port balls to provide predictable flow characteristics and smooth modulation. Multiple V-port angles are available and selected based on the specific process requirements, allowing SPC engineers to optimize Cv, control resolution, and pressure recovery.
A tight stem-to-ball connection minimizes mechanical lag, improving repeatability and response under continuous modulating service. This design enables accurate control over a broad operating range while maintaining the durability required for demanding industrial environments.
Benefits
- High Capacity with Accurate Modulation
Delivers superior control versus traditional full port ball valves due to the characterized ball and multiple trim reduction options, offering tighter control and increased capacities.
- Precision V-Port Control
Machined V-port ball geometries provide predictable flow characteristics and stable throttling across a wide operating range, delivering true control valve performance.
- Multiple Seat and Shutoff Options
Available with RTFE and metal seats, including bi-directional and uni-directional configurations, supporting shutoff classes from Class IV through Class VI, Bubble Tight, Zero Leakage, and API 598.
- TCB1 Trunnion and FCB1 Floating Platforms
Two proven mechanical designs allow the valve to be matched precisely to pressure class, size, and service severity, without compromising control performance.
- Severe Service Ready
Robust construction, material options, and seat designs support clean or abrasive media, high cycle operation, and demanding process conditions.
- Live-Loaded Packing System
Standard live-loaded PTFE or graphite packing maintains consistent stem sealing, compensates for thermal cycling and wear, and supports long-term emissions control.
