Throttle valves and exhaust flap systems for use onroad
In Germany, a third independent braking system is required for onroad vehicles like buses and lorries which exceed a total permissible weight of 5.5 t or 9 t respectively. The purpose of this statutory regulation is to be able to safely hold a fully loaded utility vehicle (e.g. HGV, truck or bus) at a gradient of 7 % and a speed of 30 km/h with the aid of a third braking system. Exhaust flaps from Klubert + Schmidt contribute to meeting this legal requirement. Moreover, our products provide important and essential support in observing European and international emissions standards. How the Euro I to Euro VI standards developed can be seen in the following graphic.
Onroad product benefits
- Long service life
- Lower maintenance costs
- Lower pressure drop through the valve
- Low internal and external leakage
- Low procurement costs and very low energy costs
The development of emissions standards Euro 1 to Euro 6
NOx emissions (nitrogen oxide)
CO emissions (carbon monoxide)
HC emissions (hydrocarbons)
Other international standards (EPA, JPN etc.) show similar developments.
