The Märkisches Werk GmbH (MWH) ball spring rotator (BSR) is a device developed to improve the quality and function of the proven ball and spring rotation mechanism. It provides reliable valve rotation for many operating hours. As a result valve life can be very significantly extended.
Simplex-Turbulo has added the BSR valve rotator to their range of spare parts and Richard Blair, who is responsible for their purchase, is very excited about this particular component, developed as a result of specific requests from customers for a more robust and reliable rotator.
“Every detail of these valve rotators is designed with the engineer in mind,” enthuses Richard. “Robust and high quality, the rotators can be disassembled and each individual part can be replaced. There is even a small indentation in the metal so you can check the valve is spinning. Honestly, it is a work of art”.
Customers clearly think so too. Over the last two weeks Simplex-Turbulo has sold over 72 BSR valve rotators, and purchased an additional 32 to add to the stockholding. Why the sudden demand? Although there are clear technical advantages to the BSR, Richard thinks the main reasons behind the increased sales are essentially practical. “In fact I think these recent orders for the BSR have been supply-driven; the BSR seems to have an excellent lead-time” he suggests. “Of course the high quality of these components is taken as read”, he adds.
This is hardly surprising, since the German manufacturers, Märkisches Werk Halver GmbH (MWH), have been highly respected makers of cylinder head components for many decades, with a consistent commitment to R&D. The MWH BSR outperforms standard valve rotators and provides more reliable and constant valve rotation over the entire operating range of the engine. This ensures sufficient valve rotation even in adverse conditions.
