Air Horn Actuator Valve
Velvac®

The Air Horn Actuator Valve (Part Number: 032243) is a component of a truck's air horn system. This valve is responsible for controlling the flow of air to the air horns, which produces the loud and distinctive honking sound that trucks are known for. When the driver presses the horn button, an electrical signal activates the actuator valve, allowing compressed air from the truck's air tank to flow through the valve and into the horns. The actuator valve typically has two positions - one for sounding a short blast and another for sounding a longer blast. This component is essential for ensuring that a truck's horn functions properly and can alert other drivers of potential hazards on the road.
