"We made good experiences with the actuators NVKC24A-MP-RE. We have been using them for three years now and we benefit from the upgrade to these devices." Having in mind that high reliability was given top priority at the beginning of this project, he adds: "The most important thing is: three years of virtually failure-free operation. The failure rate in three years of use was the lowest we have ever had for the total of 3 500 owned heating substations."
“One thing that impressed us was having such intelligence right on the valve actuator, You can characterize a coil’s performance with just a couple of pieces of data and with that information you can observe the degradation of coils and refocus your maintenance efforts accordingly. That’s very useful when you are a campus dealing with limited maintenance resources.”
