- 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. The outlet temperature gauge (optional) verifies the fluid temperature in the circuit. The FlowCal+ can also be used in hydronic systems.
- Automatic hot water circuit balancing: Installed on each return branch of the recirculation circuit, the dynamic modulating valves automatically balance the recirculation circuits to ensure constant flow.
- Quiet operation: Replaceable patented anti-scale, low noise polymer flow cartridge provides specified flow rate (gpm), with no field balancing or adjustments.
- Union connections: Compact design featuring union end connections and Press fittings for ease of installation and maintenance
- Multi-functional: Built-in check valve to protect against circuit thermo-siphoning. Built-in filter screen. Optional outlet temperature gauge to verify water temperature.
- Application flexibility: Designed for balancing domestic hot water recirculation systems, but also suitable for non-potable applications.
- High value balancing: Especially suited for hot water recirculation balancing, FlowCal+ maintains pre-determined constant flow in circuits, regardless of differential pressure changes across them.
