KQFF-A-A

This type of valve is widely used in pneumatic or hydraulic braking systems of trucks, construction machinery, agricultural machinery, or large commercial vehicles. Its core function is to directly control the supply or exhaust of air (or the flow of hydraulic oil) to the vehicle's brake chambers by manually pressing (or pulling up) the control lever with a red button, thereby achieving the vehicle's parking brake, emergency brake, or forced release of the brake.
