Stainless steel manifold with dynamic flow balancing

Stainless steel 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÷70 °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); scale 0,5÷5 l/min (HF).

The kit includes:
- delivery manifold with flow meters with fluid shut-off function;
- return manifold with dynamic flow balancing valves and manual handwheel (M30 x 1,5 mm connection), pre-arranged for thermo-electric command via R473/R473M actuators that can be installed after fitting the relative R453FY002 ring nut (to be ordered separately);
- pair of end pieces with self-sealing complete with drain cocks, manual air vent valves and specific R74 key;
- R588Z metal brackets;
- R73PY010 key for presetting.

Notes
