Belimo C225QPT-G – PI zone valve
2-way pressure-independent zone valve designed for closed-loop water systems and water-side control in ventilation and heating systems. The built-in pressure regulator maintains a flow rate corresponding to the valve position at a differential pressure of 16...350 kPa.
Key features
- DN 25, PN 25; Rp 1" female thread.
- Nominal flow rate V'nom 2100 l/h (0.583 l/s).
- Differential pressure ∆p 16...350 kPa; closing pressure 1400 kPa.
- Measuring ports (P/T) at the valve inlet and outlet allow measurement of the pressure drop across the valve.
- Equal-percentage characteristic; bubble-tight, leakage class A.
- Medium temperature -20...120°C [-4...248°F]; with actuator 2...90°C.
