Characterised ball valve
NVCB 7000
Motorised 2-way and 3-way ball valves for HVAC systems. Forged brass body, PN20 and sizes DN15 to DN50.
Nenutec motorised ball valves
Motorised ball valves with Nenutec actuators (Poland) for HVAC systems, in 2-way and 3-way versions, all rated PN20. The technical datasheet specifies seat leakage of 0.01% of Kvs.
Their characterising disc makes them particularly suitable for proportional water flow control in mixing or diverting applications, depending on valve configuration.
Below you can consult the valve and related actuator documentation. Motor selection must be checked against valve size, control type and installation differential pressure.

Sizes and actuator selection
| Nominal diameter | Actuator options | Selection |
|---|---|---|
| DN15 / DN20 | NABA02 / NABM02 / NABA05 / NABM05 | Confirm close-off pressure; the valve PDF does not tabulate 2 Nm motors. |
| DN25 / DN32 | NABA05 / NABM05 | Check differential pressure and mounting. |
| DN40 / DN50 | NABA10 HN / NABM10 HN | Check differential pressure and mounting. |
The valve datasheet specifies maximum close-off pressures of 1000 kPa for DN15–DN32 with 5 Nm, and 1000 kPa for DN40–DN50 with 10 Nm. Consult the complete PDF table before selecting the assembly.
