WG9000360522, Hand brake Valve , Trailer brake Valve, HowoA7 truck Valve

Functions:

1. Parking Brake Activation:

   • The primary function of the hand brake valve is to activate the parking brake. When the driver engages the hand brake lever, the valve directs hydraulic fluid or air (depending on the type of braking system) to the parking brake mechanisms, locking the wheels and securing the truck in place. This prevents the truck from rolling or moving unexpectedly when parked.

2. Emergency Braking Capability:

   • In addition to its primary role in parking, the hand brake valve also provides an emergency braking function. If the primary braking system fails, the driver can use the hand brake valve as a backup to apply braking force and bring the truck to a safe stop. This feature is crucial for safety, particularly in emergency situations.

3. Hydraulic/Pneumatic Pressure Control:

   • The hand brake valve controls the flow and pressure of hydraulic fluid or compressed air within the braking system. It ensures that the parking brake engages and disengages smoothly by precisely regulating the pressure in the system. This contributes to the overall effectiveness and reliability of the braking system.

4. Durability and Reliability:

   • The hand brake valve on HOWO trucks is designed for heavy-duty applications, requiring durability and reliability. It is made from high-quality materials and undergoes rigorous testing to ensure that it can withstand the demands of trucking operations, including frequent use, varying temperatures, and harsh operating conditions.

5. Integration with the Overall Braking System:

   • The hand brake valve is an integral part of the truck's braking system, working in conjunction with other components such as brake calipers, rotors, and brake lines. Its proper functioning is crucial for the overall effectiveness of the braking system, enabling the truck to stop safely and efficiently.
