10100082 KL3H2-18 Relay Valve Air Brake Pneumatic Replacement Spare Part for XCMG QY25K QY65K Truck Crane

10100082 KL3H2-18 Relay Valve – OEM Replacement Air Brake Pneumatic Spare Part for XCMG QY Series Truck Crane

Maintain fast, reliable air brake response on your XCMG truck crane with this precision-engineered 10100082 KL3H2-18 Relay Valve. Designed as a direct OEM-compatible replacement for XCMG QY25K–QY65K (RZ) series truck cranes, this pneumatic relay valve amplifies and rapidly delivers brake air pressure to the wheel brake chambers, ensuring short brake response times and consistent braking force across all axles in demanding lifting and road travel applications.

Key Features

• OEM-Compatible Fit: Engineered to match original XCMG 10100082 / KL3H2-18 specifications for a direct drop-in replacement — no modifications required.
• Rapid Brake Response: Relay valve design amplifies the pilot signal from the brake pedal valve and delivers full brake chamber pressure almost instantaneously, minimizing brake lag on multi-axle crane configurations.
• High Flow Capacity: Large-bore internal passages ensure rapid air volume delivery to brake chambers for consistent, powerful braking performance under full load conditions.
• Precision Pressure Regulation: Factory-calibrated internal piston and spring mechanism ensures accurate, proportional brake pressure output matching the driver’s pedal input.
• Heavy-Duty Construction: Robust valve body and internal components engineered to withstand continuous air pressure cycling, vibration, and temperature extremes in heavy crane applications.
• Direct Port Connection: OEM-matched port configuration for plug-and-play installation with the existing pneumatic brake circuit — no line modifications required.

Why Choose This Part?

The relay valve is a safety-critical component in multi-axle pneumatic brake systems. A worn or leaking relay valve causes delayed brake response, uneven braking force distribution, and increased stopping distances — serious safety risks for a loaded crane traveling on public roads or jobsite grades. Sourced from experienced manufacturers specializing in XCMG pneumatic brake components, each 10100082 KL3H2-18 relay valve undergoes pressure response and leak testing before shipment to ensure it meets OEM safety standards.
