Technopolymer pre-assembled modular manifold for HVAC systems, with dynamic flow balancing and independent setting for each individual circuit.
Outlets connections for copper, plastic or multilayer pipe adapters.
Center distance between the outlets 50 mm.
Temperature range 5÷60 °C.
Max. working pressure 6 bar (10 bar for system testing).
Available in two versions: Low Flow (LF) e High Flow (HF).
Flow rate setting range for each individual circuit: 20÷160 l/h (LF); 10÷250 l/h (HF).
Working differential pressure range: 20÷60 kPa (LF); 30/40÷150 kPa (HF).
Flow meters: scale 0÷2,5 l/min (LF); double scale 0÷5 l/min and 0÷1,5 GPM (HF).

The kit includes:
- delivery manifold with flow meters and lockshields for fluid shut-off function;
- return manifold with shut-off valves with manual handwheel (connection M30 x 1,5 mm), pre-arranged for thermo-electric command via R473/R473M actuators that can be installed after fitting the relative ring nut R453FY002 (included with the kit) on the module;
- pair of R269T multifunction valves;
- R588ZP metal brackets;
- R73PY010 key for presetting.

Optionals
- R500-2: flush-mounting metal cabinet, with adjustable depth.
- R473, R473M: normally closed thermo-electric actuators.
- R73FPY001: pair of spanners for removing the manifold modules.
- R178E, R179E: 3/4”E adaptors.

Spare parts

- P553FPDB002: return module with dynamic High Flow balancing bonnet and 3/4”E outlet.
- P553FPY005: cap module.
- P553FPY006: inlet module (without nut).
- P553FPDB020: kit composed of delivery module with flow meter with scale 0÷2,5 l/min + return module with dynamic Low Flow balancing bonnet and 3/4”E outlets.
- P553FPDB021: kit composed of delivery module with flow meter with double scale 0÷5 l/min <(>&<)> 0÷1,5 GPM + return module with dynamic High Flow balancing bonnet and 3/4”E outlets.
- P583Y004: nut and gasket for inlet module.

Manifolds with dynamic flow balancing are equipped with a data-tag with the "DB series" identification, the flow and Δp characteristics for both versions of the manifolds: Low Flow and High Flow.

For connection to the pipe use the base 3/4"Eurocone adaptors
