The EVB exhaust brake butterfly valve is a key component for auxiliary braking of truck engines. Especially when the vehicle is descending a long slope, using butterfly valve slow braking can significantly reduce the wear of the service brake, greatly reducing maintenance costs and safety failures.
BHKS is the largest manufacturer of exhaust brake valves in China, with an annual production of 500000 EVB butterfly valves, ranking first in the domestic market in terms of production and sales volume.
At present, based on the existing pneumatic EVB valve and matching the customer's requirements, we have designed an electronic EVB valve with higher control accuracy.
The electronically controlled exhaust gas recirculation valve (EGR) can open, close, or adjust exhaust gas recirculation. The engine undergoes exhaust gas recirculation and reburning, resulting in a decrease in combustion temperature and a significant reduction in the generation of nitrogen oxides.
BHKS provides pneumatic EGR valves and electric EGR valves to meet the emission values stipulated by the laws of commercial vehicle country VI, and also produces one-way valves for the EGR system.
The working principle of an electronically controlled exhaust throttle valve (ETV valve) is similar to that of an engine brake valve, and its position depends on the vehicle type. It is usually located in the exhaust pipe and connected to the rear end of the exhaust turbocharger.
By using throttle valves, many engine functions can be achieved, such as thermal management or cold start optimization, gear shift support, particle filter regeneration, etc.
The one-way valve can control the direction of engine intake and exhaust, and can be widely used in diesel engines and natural gas engines with different displacement.
The cylinder is a driving device designed specifically for valve products, with features such as compact structure.
