After an insurance recommendation I decided to replace one of our Safety Relief Valves. Working within the pharmaceutical industry, the valve was required for hot water calorifier.
The service on the site was great and I liked the fact that the certifications arrive with the products. We at Bayer have limited access to wholesalers, buying direct from NABIC using a bank card proved to be a much easier transaction.
