Pressure-Independent Control Valves
Bell & Gossett’s Ultra Setter line of pressure-independent control valves combines easy field adjustability with excellent flow control, making them an energy-efficient solution for a HVAC system. The key feature is Ultra Setter’s combined flow setting and modulating control element. The maximum flow is set using the gpm dial and controlled inside the valve through a rotational flow-setting motion. The branch flow rate is controlled through use of an external control actuator, which operates the linear control stroke. The valve’s internal differential pressure regulator maintains the desired flow rate as system pressures fluctuate.
