We had an existing NABIC Fig. 500 safety valve installed in our steam boiler factory which needed replacing. The valve had started to leak due to its old age.
I had no hesitation in purchasing another as it’s been a great product. I was very happy with the service of the website, as well as the prices. The fact the valves come with the necessary certifications is also great.
