DZ95259360105 X3000/M3000 Relay Valve

The DZ95259360105 X3000/M3000 Relay Valve is a key part of the braking system for SHACMAN X3000 and M3000 heavy-duty trucks. It controls the pressure transfer in the brake circuit, amplifying the brake signal from the driver’s pedal and quickly sending high-pressure air to the wheel brakes—this lets the truck brake stably and responsively, which is super important for safety during long-haul transport, heavy-load hauling, and downhill driving. We use good materials and precise pneumatic tech to make it: the valve body is high-strength aluminum alloy—light and not easy to rust. The internal valve core is a wear-resistant engineering plastic with low friction and long-lasting. The sealing rings are imported nitrile rubber—can handle high pressure and oil. The interface specs match the original brake pipes of SHACMAN X3000/M3000 perfectly, so it connects tightly to the air pipes with no leaks. It handles tough conditions—extreme temps (-40℃ to 80℃), high humidity (95% non-condensing), and vibration (5-500Hz)—without the valve body cracking, valve core jamming, or seals aging. Swapping it is easy: no need to modify the brake pipes or mounting bracket, just disconnect the old valve’s air pipes, take off the fixing bolts, install the new one, and tighten the bolts to 15-18N·m. Before shipping, we test ‘em strictly: check air tightness (no leaks at 1.0MPa), pressure response (≤0.3s), and 5000-cycle fatigue test—so it’s reliable.

Product Description

We use good materials and precise pneumatic tech to make it: the valve body is high-strength aluminum alloy-light and not easy to rust. The internal valve core is a wear-resistant engineering plastic, low-friction, and long-lasting. The sealing rings are imported nitrile rubber-can handle high pressure and oil.

Swapping it is easy: no need to modify the brake pipes or mounting bracket, just disconnect the old valve's air pipes, take off the fixing bolts, install the new one, and tighten the bolts to 15-18N·m.

Features And Advantages

① Fast braking: ≤0.3s pressure build-up, 30% faster than ordinary valves-shortens heavy-truck braking distance.

② Stable pressure: 0.7-0.8MPa steady output, no brake fading-consistent braking force.

③ Fits X3000/M3000 exactly: Pipes, holes, and connectors match. No adapters, saves 25% maintenance time.

④ Durable & leak-proof: Anti-corrosion valve body, 3+ years no leaks, 300k+ km service life.

Application Scope

Only SHACMAN X3000/M3000 trucks (tractor, dump, cargo, mixer with original brake system). No other SHACMAN models or FAW/Dongfeng-different pressure/pipes/space, won't fit.
