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.

2-way and 3-wayPN20DN15–DN50
Characterised ball valve NVCB 7000

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.
