Rheinmetall’s big orders for back pressure valves
By Mike Brezonick17 August 2021
Rheinmetall announced it has secured two significant orders totaling €37 million for back pressure valves for commercial vehicles. The company said “a well-known engine manufacturer from China” has ordered intelligent electronically commutated back pressure valves for 12 L diesel engines. Meanwhile, a South American customer has placed an order with the company for pulse width-modulated back pressure valves for 3.8, 4.5 and 6.7 L engines.
Delivery of the parts earmarked for China will take place in the 2021-2025 timeframe, Rheinmetall said. In keeping with the company’s “local for local” principal, the valves will be produced in China. The components slated to go to South America will be manufactured at Rheinmetall’s plant in Ústi and Labem in the Czech Republic and shipped from 2022 to 2027.
Both orders will be coordinated by Rheinmetall subsidiary Pierburg GmbH of Neuss, the group’s specialist for emission-related components.
Back pressure valves are designed to help reduce engine exhaust emissions and optimize fuel consumption. The valves are integrated into the engine control management via customer-specific interfaces, while flexible adaptation of the flange geometry makes it possible to install the valves in different types of vehicles, the company said.
The modular design of the back pressure valves makes them equally suitable for light-, medium-, and heavy-duty vehicles, Rheinmetall said. Moreover, the components for commercial vehicle engines are specially designed to withstand heavy vibration, temperature and pressure stress.
