HALVER, GERMANY - March 7th, 2025 - Save the date! 📅

In less than 3 months, CIMAC Congress 2025 in Zürich kicks off. The CIMAC Congress Technical Program is the core of the event and one of the most important international conference programs in the field of large engines, power, drives and propulsion, where the entire industry comes together to review and discuss technical, environmental and regulatory trends, developments, opportunities and challenges.

Märkisches Werk is honored to contribute to the Technical Program again in 2025 with a paper from Dr. Janis Kimm entitled "1st methanol generation of valve spindles and seat rings for newbuildings and retrofit". This paper presents results from a field test and test series of a bespoke model test rig, aiming to develop the first generation of methanol valve spindle and seat ring pairings for intake and exhaust. For this purpose, the effects of methanol and its combustion by-product methanoic acid on the wear behavior of typical valve and seat ring materials were investigated.

Please stop by our booth number 37 in the Gartensaalfoyer to talk with our technical team!

HAMBURG, GERMANY - September 6th, 2024 - Today marks the end of an exciting week at SMM Hamburg and we are thankful for every customer, guest and friend that came by our (new) booth to talk with us. We can't remember a trade show with more engaging and substantive discussions than we've had this week.

There is no doubt that the MWH Team is leaving Hamburg today with renewed excitement and motivation to solve the valve train challenges of tomorrow, whatever and wherever they may be.

We're already looking forward to SMM 2026!

HALVER, GERMANY - September 15th, 2024 - SMM Hamburg is now less than three weeks away and we couldn't be more excited to welcome customers from around the world to our new booth.

Come by our Stand 405 in Hall A04 to meet our team of experts and discover our latest innovations, including:

✔ MW WR Superalloys for maximum valve & valve seat wear resistance
✔ MW NiClad to repair cylinder head cavitation damage
✔ Methanol-ready intake & exhaust valves & seat rings
✔ Cutting-edge reconditioning services to improve total cost of ownership

See you there!

HALVER, GERMANY - September 30th, 2024 - Based on field experience with methanol, extensive material compatibility tests and experience from almost 80 years of valve production, Märkisches Werk GmbH is proud to launch our 1st generation of valve spindles and seat rings for new builds and retrofits using up to 100% methanol injection.

We began this journey several years ago studying the boundary conditions within the combustion chamber. Methanol is a potent cleaning agent which means the typical wear-protective tribofilm formed on the valve seat by carbon-based fuels and lubrication oils is not present, resulting in rapid wearing metal-on-metal contact. That combined with combustion by products such as formic acid presents a unique compatibility challenge for valves and seat rings due to severe tribocorrision.

With that experience in mind, we began exhaustive material compatibility testing to understand the tribocorrision behavior of different base material and hardfacing combinations within the methanol environment. We found that, compared to leading commercially available hardfacing alloys, MW WR Superalloys exhibited the lowest wear values in every compatibility test performed to-date.

Our quest for perfection never stops, thus our 1st generation of valve spindles and seat rings for new builds and retrofits using up to 100% methanol injection is only the beginning. Our customers can be confident that we’re doing our homework so that their methanol engines equipped with these components are ready to do the hard work.

HALVER, GERMANY - September 24th, 2024 -Märkisches Werk GmbH is proud to formally introduce our family of valve spindles and seat rings featuring our proprietary hardfacing alloys, now formally known as MW Wear Resistant (WR) Superalloys.

Almost a decade ago, MWH began developing bespoke, application-specific hardfacing alloys for high performance gas and ultra low-sulfur engine applications. Experience showed that many commercially available hardfacing alloys were simply not capable of meeting the industry's increasing performance and TBO requirements, so we decided to develop our own hardfacing alloys. In recent years, this work has expanded to include hydrogen, methanol and ammonia applications.

MW WR Superalloy products take a systematic approach to the valve & seat ring pairing that encompasses everything from raw material chemistry and grain size, CNC welding parameters, heat treatment, pre- and final-machining and, of course, perfectly matched tribological armoring of valve and seat ring. In our opinion, this philosophy is the only way to truly maximize engine performance, reduce downtime and extend the engine's useful life.

Until today, we have simply referred to MW WR Superalloys as "proprietary MWH hardfacing alloys". Many customers have in fact been operating their engines with valves and seat rings armored with different MW WR Superalloys for almost a decade. But with ever-increasing engine performance requirements, we felt it appropriate to give this increasingly important product line a proper name.

HALVER, GERMANY - June 18th, 2024 - Märkisches Werk GmbH has developed MW NiClad, a novel and sustainable process to repair and reconstruct cast iron cylinder heads damaged by cavitation that would otherwise have to be discarded.

The cylinder head repair process begins by machining off the portions of the cooling water sealing surfaces and seat ring pockets damaged from cavitation and then applying MW NiClad via cladding. The entire cylinder head undergoes a pre- and post-cladding thermal treatment to eliminate residual stresses before the final machining steps return the cylinder head to its original condition and dimensions. The time between overhauls (TBO) of a MW NiClad-treated cylinder head is equal to that of a new cylinder head, thereby extending its lifetime and reducing total cost of ownership.
