Your certified specialist for precise process observation. We develop customized sight glass fittings for your individual requirements.

From dealer to manufacturer, ACI now specializes in the design and production of industrial valves.
Our customers include renowned companies from the chemical, petrochemical, and energy sectors, as well as container and plant construction, shipbuilding, and universities. With the new location in Jülich, we are creating optimal conditions for further growth and higher storage capacities.
Flexibility and quick response times define our experienced team.

As Ebora BV, we would like to share our exceptionally positive experience with ACI valves. Recently, we faced the challenge of producing two special tubular sight glasses that need to withstand extreme conditions – a working pressure of 25... and working temperatures of -101°C to +100°C. These specific requirements exceeded the usual specifications by far and required a customized solution that was only feasible through exceptional expertise and technical competence. ACI valves not only accepted this challenge but mastered it with flying colors. Thanks to their dedicated team and extensive experience in the design and manufacturing of customized solutions, they were able to fully meet our special requirements. Their ability to develop their own design and achieve certification according to PED 2014/68/EU Module H significantly contributed to the success of this project. The collaboration with ACI valves was consistently positive. From the initial concept to the final acceptance by our customer, ACI valves only needed 8 weeks – an impressive timeframe that highlights the efficiency and commitment of their team. Their transparent communication and customer-oriented approach simplified and improved the entire process for us as partners. We at Ebora BV are proud to have ACI valves as our supplier. Their outstanding performance and reliability have made them a valuable partner on whom we can continue to rely in the future. We look forward to further successful projects with ACI valves and recommend their services and products to anyone seeking high-quality, customized solutions.
