Sinotruk Howo T7H T5G Hand Brake Valve WG9000360522

The WG9000360522 Hand Brake Valve plays a fundamental role in the heavy-duty commercial air brake system. By regulating compressed air pressure sent to or exhausted from the spring brake chambers, this Howo hand brake valve allows the driver to engage or disengage the parking brake system securely during stationary parking or emergency stopping situations.

Manufactured in ISO9001-certified facilities using high-tensile steel and precision internal rubber seals, the WG9000360522 control valve ensures immediate pneumatic response and leak-free performance under extreme pneumatic operating pressures. Replacing a worn, leaking, or sticking unit with a 100% brand-new WG9000360522 hand brake valve eliminates air pressure leaks, prevents unintentional brake drag, and guarantees commercial fleet safety compliance.
