Function
The FlowCal™ automatic flow balancing valve maintains a
constant fixed flow rate within varying system differential
pressure ranges. Operation is fully automatic requiring no
manual adjustment. The 121 series utilize an exclusive,
interchangeable flow cartridge, made of anti-scale, low
noise polymer for use in cooling and heating systems. The
