Balancing valves

R280KL Light kit for terminal units (fan coils)

Preassembled light kit combining the components required for balancing, control, flushing and commissioning of HVAC terminal units (fan coils, chilled beams, etc.) with the main distribution network.
The kit consists of a double ball diverting valve for by-pass and maintenance of the unit, a Y-filter, a pressure independent
control valve (PICV), a drain cock and two pressure ports to measure the flow rate.

Temperature range: 5÷110 °C.
Max. working pressure: 25 bar.
Working differential pressure range: 25÷400 kPa or 25÷800 kPa depending on the installed actuator.
Actuator connection: M30 x 1,5 mm.
Main components: EN 12165 CW602N (DZR) brass

Working flow rate range:
R280KLY000: 32÷520 l/h (single setting scale)
R280KLY001: 150÷380 l/h (LF); 180÷630 l/h (HF)
R280KLY002: 290÷1000 l/h (LF; 860÷1500 l/h (HF)
