Description
The 2FSA.
B valve family is designed for precise flow control in heating, cooling and industrial HVAC systems where high differential pressure and low leakage are required. Thanks to the balanced plug design, these valves ensure stable regulation and reliable shut-off even under demanding operating conditions.
With a robust spheroidal cast iron body and globe valve construction, the 2FSA.
B series is particularly suitable for applications with high pressure and high ΔT, such as overheated water and steam systems. The balanced internal design reduces actuator load while maintaining accurate and repeatable control performance.
