Control for valves utilizing an inflatable sealing system
We worked with the company’s development department to address issues in their dedusting systems for coal-fired power plants and aluminum plants. The systems are used internationally. The valve seals were regularly destroyed, allowing dust to penetrate the control system and causing major damage and system outages.
SCOPE: Development of a control solution for a dedusting system.
WHO: A market leader in dedusting systems for coal-fired power plants and aluminum plants.
WHAT: Development of a robust control system
HOW: We developed a control system with a small pneumatic control block and a smart circuit board in a relatively small housing.
WHERE: Worldwide
WHEN: From 2019
Developing a Robust System for a Dusty Environment
To meet the unique challenges of this harsh operating environment, we had to develop a control system that was small, robust in dusty environments, and resistant to impacts. The control system had to be easy to operate and suitable for international use, and the customer’s specifications had to be strictly adhered to.
We developed a control system with a small pneumatic control block and a smart circuit board in a relatively small housing. To ensure safe switching, delays could be installed via programmable pressure switches. The position of the valve disk and the inflatable seal were continuously monitored. As an added benefit, by monitoring the seal’s pressure, we were able to develop diagnostics that could predict a failure.
