The new 8Nm spring return damper actuator NAFA...08(S)Nm Series designed specifically for applications in the HVAC market, or light Industrial market and telecommunication module.
The high quality spring return damper actuators have been designed for use with air damper, butterfly valve, characterized ball valve and globe valve with the use of special adapters.

For air control dampers up to approx. 1.5 m2 features include:

The NVCB Series of electrically automated characterised ball valves designed specifically for the HVAC market are now available.
The high quality automated ball valves combine the performance of globe valves with the economy of ball valves providing the best of both worlds. The NVCB Series ball valves are equipped with a patented characterized insert in the ball. This characterised ball design provides very high rangeability and excellent equal percentage flow characteristics.

The NVCB Series valves are ideal for all automatic temperature control applications using hot water, or chilled water. They can be equipped with a variety of economical electric actuators. Choices include on/off, 3 point and 0(2)...10VDC proportional control in non-spring return 24VAC/DC, 230 VAC. Spring return actuators on request. The NEMOTEQ electric actuators feature simplified mounting of the actuator to a direct coupled bracket. The result is a very low profile unit with flexibility of use as well as fast and easy maintenance.

The Characterised Insert establishes a flow coefficient (Kvs) similar to globe valves, eliminating the need for pipe size correction tables when sizing valves. They provide superior rangeability and equal percentage flow characteristic.

The low torque facilitates the use of smaller, less expensive actuators that extends valve and actuator service life. The 3 - way Ball Valve has a “ T piece “ design that simplifies 3-way piping allowing for 3-way Ball Valves to retrofit globe valves.
