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 500,000 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.
