Metso positioner issue
Thread Content
I would like to ask the experts: How is the Metso locator NDX1510 performing? Have you encountered any issues with poor sealing of the casing leading to water leakage? Thank you.
We are a valve manufacturing factory. Last July and August, due to a temporary shortage of Yamatake AVP series positioners, we used a batch of Metso NDX1510 positioners as a temporary solution. According to the feedback from our assembly workers, their performance was not good: firstly, installing them with a linear stroke was somewhat troublesome, and secondly, it was difficult to get the positioners to stay at the set position – the signal generated by the signal generator caused the positioners to fluctuate within a 3% range; this issue has occurred with three units already. I’ve never encountered a situation where the enclosure’s seal wasn’t good enough to prevent leakage; to be precise, I don’t know how it performs in actual use.
