Hand Brake Valve WG9525360505 Hohan DETAILS :
The hand brake valve (commonly known as "handbrake valve", "parking brake valve" or "spring brake valve") is one of the
most critical safety control components in the braking system of trucks . Its core function is to control the application and
release of the truck parking brake (spring brake air chamber), and it also has an emergency brake function.
Its specific functions and working principles are as follows:
Function 1: Control parking brake (parking brake)
Apply parking brake (parking/parking):
When the driver needs to park (especially parking on a slope) or leave the vehicle for a long time, pull up the handbrake
valve handle.
This operation empties the compressed air to the spring brake air chamber of the rear axle (and sometimes the front axle).
After losing the reverse thrust of the air pressure, the powerful pre-compressed spring inside the spring brake air chamber
expands rapidly, pushes the push rod, and strongly locks the wheel through the brake cam or the brake air chamber push rod
to achieve reliable parking. This is the most commonly used and most important function.
Release parking brake (prepare for driving):
When the driver needs to start driving, press the handbrake valve handle (usually a button on the handle).
This operation connects the compressed air from the air reservoir and fills the spring brake air chamber.
The powerful thrust generated by the compressed air overcomes and compresses the spring inside the air chamber.
Function 2: Provide emergency braking function
Emergency situation during driving: If the service brake (foot brake) system suddenly fails completely during driving,
the driver can quickly pull up the handbrake valve handle.
So.Lets chosse a high quality Hand Brake Valve to ensure our safty of the driver and the long lift of truck ,please.
