Pressure independent control valves. VSX..PB/VSXT..PB pressure independent balancing & control valves can be used in heating and cooling systems in applications with Fan Coil Units, Chilled Beams or other terminal units applications. VSX..PB/VSXT..PB valves provide modulating control with full authority regardless of any fluctuations in the differential pressure of the system. VSX..PB/VSXT..PB valves combine an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve. VSX..PB/VSXT..PB valves make it simple to achieve 100% control of the water flow in the building, while creating high comfort and energy savings at the same time.
An additional benefit is that no balancing is required if further stages are added to the system, or if the dimensioned capacity is changed. Energy saving is due to optimal control, lower flow and pump pressure. Maximized ΔT is due to faster response and increased system stability.
