- The FlowCal+™ compact dynamic flow balancing valve is pressure independent and maintains a fixed flow rate as differential pressures vary. It incorporates an exclusive flow cartridge, made of an anti-scale, low noise polymer. Constructed of DZR low-lead brass, FlowCal+ is ideally suited for use in plumbing applications such as hot water recirculation systems. The built-in check valve protects against circuit thermo-siphoning.
- FlowCal+™ series is designed for domestic hot water recirculation systems, to speed hot water delivery, reduce water waste and save energy
- Installed on each return branch of the recirculation circuit, the dynamic modulating valves balance the recirculation circuits to ensure constant flow
- Factory assembled and tested with a selectable flow cartridge for 0.5, 0.75, 1.0, 1.5 or 2.0 gpm with pipe sizes 1/2, 3/4 or 1 in C or press
- The built-in check valve protects against circuit thermo-siphoning, the optional outlet temperature gauge verifies the water temperature
- Replaceable patented anti-scale, low noise polymer flow cartridge provides specified flow rate (gpm), with no field balancing or adjustments
