Balancing valves

R280KC Compact kit for terminal units (fan coils)

Preassembled compact 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 diverting ball valve to bypass the unit, a full-port ball valve with integrated filter, a pressure independent control valve (PICV) with its flow rate setting key, a draincock and four pressure ports to measure the differential pressure and the flow rate.

Temperature range: 5÷120 °C.
Max. working pressure: 25 bar (2,5 MPa).
Working differential pressure range: 25÷400 kPa or 25÷800 kPa depending on the installed actuator.
Actuatorconnection: M30 x 1,5 mm.

Working flow rate range:
R280KCY000: 32÷520 l/h (single setting scale)
R280KCY001: 150÷380 l/h (LF); 180÷630 l/h (HF)
R280KCY002: 290÷1000 l/h (LF; 860÷1500 l/h (HF)
R280KCY003: 600÷3500 l/h (single setting scale)
