Product Detail

1070500009 Exhaust Brake Butterfly Valve Zoomlion truck crane

The 1070500009 Exhaust Brake Butterfly Valve is an OEM spare part for Zoomlion truck cranes. It is a critical component of the auxiliary brake system. Designed to assist the primary service brake, the exhaust brake helps slow the vehicle and reduces wear on the main braking system during operation.

Auxiliary Braking Function: The valve is part of the auxiliary brake system, which, along with the service brake and parking brake, ensures comprehensive vehicle control .
Variable Valve Exhaust Brake (VVEB): Zoomlion documentation identifies the system as VVEB. When activated, it restricts the engine's exhaust flow, creating back pressure that helps decelerate the crane .
System Integration: The exhaust brake is a component of the engine's exhaust system. The butterfly valve is controlled to open and close, regulating exhaust gas flow to achieve the braking effect. The system can be temporarily deactivated by pressing the clutch pedal or engine control pedal.
Safety Enhancement: Using the auxiliary exhaust brake prolongs the service life of the service brake components and improves overall safety, especially during long descents or when carrying heavy loads. It is also a key safety component for vehicles carrying heavy loads.
