Operational stability and longer service life with MAC pulse valves is the expectation at NLMK DanSteel, after another delivery and installation from Hans Buch has been put into operation. At NLMK DanSteel, they particularly notice Hans Buch’s quick response time and quick follow-up to changing needs.


Hans Buch has delivered and installed 56 pulse valves from MAC Valves to NLMK DanSteel, with whom Hans Buch has collaborated on several occasions.

The collaboration between Hans Buch and NLMK DanSteel is one of many examples that we not only deliver what was agreed on time, but that we create value for the customer with a quick response, as well as quick follow-up and handling of changes and additions.

MAC pulse valves adjusted to NLMK DanSteel’s unique needs

The 56 MAC pulse valves are installed in eight individual sections consisting of a series of seven pulse valves each. Each of the 56 pulse valves serve six bag filters, which NLMK DanSteel needs efficient cleaning of.

The setup allows for a large number of individual and serial settings, where a given sequence is programmed. In addition, the pulse valves are adjusted in pulse time and frequency to the unique task in NLMK DanSteel’s application.

Compared to conventional diaphragm valves (also known as “diaphragm valves”), MAC’s pulse valves give NLMK DanSteel a number of advantages.

Hans Buch’s product manager: “The exact level between precise performance and energy consumption”

The advantages include, among other things, energy savings, longer service life, as well as less maintenance and less downtime. This is made possible by the unsurpassed precision of the pulse valves, which ensure efficient performance with the least possible air consumption.

After installation, we at Hans Buch, in collaboration with NLMK DanSteel, will adjust the performance of the pulse valves, where the proper level for the customer’s needs has been identified. This is explained by Per Lykkebæk Larsen, product manager for Pneumatics at Hans Buch Industry.

– Pressure, pulse time and sequence for the valves must be adjusted to achieve the perfect balance between differential pressure over the bag filters and the correct air consumption. Along with the prevention of air leaks, it provides the best conditions for optimal energy consumption, which overall provides cost savings for the customer, he says.

NLMK DanSteel: Operational stability and longer service life on bag filters

With both delivery, installation and the right adjustments, the 56 pulse valves are ready for operation. It is still too early to conclude the excat benefits of this delivery, but at NLMK DanSteel, they rely on the benefits from a previous similar delivery of MAC pulse valves from Hans Buch.

Janus Hansen, maintenance supervisor at NLMK DanSteel, explains that the pulse valves from MAC have had a beneficial effect on both the uptime of the plant in question and the lifetime of the bag filters.

– The first project with MAC pulse valves has now been in operation for almost two years without any problems with the installed valves. The biggest benefit has been the operational stability, as well as the so far longer life of the filters in the plant where they are installed, he says.

“The biggest benefit is operational stability”

Experienced collaboration with another successful process

At Hans Buch we are proud of another successful delivery of MAC pulse valves. Our collaboration with NLMK DanSteel reflects our ambition to provide a good service for our customers, who get a better experience than just delivery of components at the door.

Prior to delivery, we search for the customer’s detailed needs and demands, and we offer, among other things, to calculate the return of investment (ROI) with the customer’s data if requested. Along the way, we keep the customer informed and adapt to the changed needs that may arise, and after the task has been completed, we follow up on whether the agreed delivery and solution meet the customer’s expectations.

– At Hans Buch, we believe that it has been a successful process with the delivery at NLMK DanSteel, where we have also gained valuable experience for future supervision of installation tasks internally between our sales engineers and product managers and externally with our service partners, says Per Lykkebæk Larsen.

The experience with Hans Buch receives highly notable words from NLMK DanSteel after the new delivery of pulse valves from Mac Valves. Here, Janus Hansen is specifically highlights that Hans Buch’s specialists have responded and acted quickly on questions and adjustments during the entire process.

– There has always been a quick response time to inquiries, and if there has been a need for further investigations, this has also been dealt with quickly. In addition, they follow up on the tasks after completion, and any errors are quickly corrected, he tells.

– The words we primarily associate with Hans Buch as a supplier and partner are credibility and care in the execution of the task from start to finish, including follow-up and possible commissioning of the solution, concludes the maintenance supervisor at NLMK DanSteel, Janus Hansen.
