FlowCal pressure independent balancing valves maintain a fixed flow rate within varying system differential pressure ranges. The design incorporates an exclusive flow cartridge, made of an anti-scale, low noise polymer and a compact DZR low-lead brass valve body for use in hydronic and domestic water systems. The FlowCal eliminates the need for onsite measurements and trial and error flow rate setting as required with manual calibration valves. It is ideal for applications including open fan coil systems and hot water recirculation balancing.
