FlowCal™ compact dynamic
automatic flow balancing valve
127 series
Function
The FlowCal™ compact dynamic automatic flow balancing
valve is pressure independent and maintains a fixed flow rate
within varying system differential pressure ranges. It eliminates
the need for onsite measurements and trial and error flow
rate settings as required with manual calibration valves.
The design incorporates an exclusive flow cartridge, made of an
anti-scale, low noise polymer and a compact low-lead brass valve body
for use in hydronic and domestic water systems.
The FlowCal balancing valve is available with NPT male, sweat, press,
PEX crimp and PEX expansion union connections. The union nut makes
installation and maintenance fast, easy and efficient for a variety of
tailpiece options.
