Belimo D7250WL/BAC – set for a 3-way system
The set comprises 2x D6250WL+ZPR01 and 2x PRCA-BAC-S2-T-250: two butterfly valves with two actuators, supplied separately for installation with a tee. The DN 250 tee is not included in the set and must be ordered separately. The system is designed for mixing, flow distribution, and switching and control on the water side.
Key technical data
- 3-way system, DN 250, PN 16; valves with threaded holes in the body, flanged connection.
- Kvs 1200 m³/h for control applications; Kvmax 3000 m³/h for switching applications.
- Fluid: water, water with max. 50% vol. glycol; fluid temperature -20...120°C [-4...248°F].
- Maximum differential pressure ∆pmax 300 kPa; closing pressure 1200 kPa.
- Actuator torque 160 Nm; rated voltage AC 24...240 V / DC 24...125 V; motor running time 35 s / 90°.
- Control: open/close, modulating, communicative or hybrid; BACnet MS/TP, Modbus RTU, MP-Bus communication.
- Operating range Y 2...10 V; available settings 0.5...10 V and 4...20 mA. Feedback signal U 2...10 V.
- Flow characteristic: 0...60% opening angle – equal percentage; 0...100% – S-shaped, with the option to configure a linear characteristic.
- Leakage rate A; protection rating IP66/67.
To control both actuators with the same signal, the control signal of one actuator must be inverted. Permitted valve mounting orientation: from vertical to horizontal relative to the stem; installation with the stem pointing downwards is not permitted.
