I. Basic Model Information
\nOriginal Part Number: WW9000360528
\nAlias: Vehicle manual brake valve, hand control valve, air-stop brake handleHandle valve, three-hole hand brake valve
\n\u00b7 Compatible models: Sinotruk Howo A7, Sinotruk T7H tractorVehicles, some T5G models
\nInstallation location: Below the cab workbench, handbrake control master
\nCheng
\nII. Product Functional Principles
\n1. Pneumatic control trailer parking\/unlockingbrake, handle valve exhaust, trailer air cutoff brakelock; release air intake, release trailer brake release
\n2. Independent control of the trailer’s airway, separation from the main driver’s brake circuit,
\nThe trailer can be locked separately.<\/p>\n
3. The three-air port structure, air intake, and exhaust have clear division of labor.
\nThe air pressure control is stable.
\nThree. Structure and Material Parameters
\n\u00b7Valve body: Die-cast aluminum alloy valve body, pressure-resistant and corrosion-resistan
\nControl handle: Aging-resistant rubber + plastic handle, positioningClarify and prevent disconnection
\n\u00b7 Air port configuration: 3 threaded air interfaces, none factory piping matchingRequires modification
\n\u00b7 Net weight per piece: approximately 0.85 kg
\n\u00b7 Pressure adaptation: Heavy truck standard air pressure operating range of 8-12 bar
\nSealing structure: multi-layer rubber diaphragm, air leakage prevention, pressure relief cardDun
\nFour. Common Replacement Fault Scenarios
\n. The handle is leaking air, the valve body is depressurized, and the hanging hand cannot be locked.Car
\n2. Push-pull handle hair clip, The gearposition does notrebound. Brake switching failure
\n3. Vent thread Wear, Shell cracking, abnormal air pressure in the airway
\n4. Replacement for vehicle aging or accident sulfur damage
\nFive. Compelitive Product Replacement Reference
