Product Overview
OE No.: DZ9618936005 Four Circuit
Protection Valve (Air Distribution Valve),original spare part for SHACMAN DelongNew M3000, X3000 heavy duty trucks. Itdistributes compressed air into fourindependent air circuits for service brake,parking brake, clutch and auxiliary airsystem. If one circuit leaks air, the otherthree circuits still maintain pressure to avoidcomplete brake failure. Die-cast aluminumhousing with premium sealing components,stable air pressure output for long-distanceand heavy-load transportation.
Compatible Vehicles
SHACMAN Delong New M3000, X3000,F3000, F2000, Aolong series trucks. Directreplacement for original air dryer assembly
Key Features
1. Four independent air circuit safety design,single circuit leakage will not affect otherbraking systems.
2. Precise internal valve core ensuresbalanced air pressure output for eachcircuit.
3. High-temperature & wear-resistant rubberseals, no air leakage under long vibration.
4. OEM standard thread ports and mountingholes, plug-and-play without modification.
5. Shock & corrosion resistant aluminum body, suitable for all harsh road conditions.
Common Replacement Symptoms
Rapid air pressure loss when one air tankleaks
Uneven air pressure between servicebrake and parking brake
Frequent air compressor running, poor airholding performance
Internal air cross-leakage inside the valveQuality Assurance
All valves pass air tightness test before
delivery. Standard export carton packaging,stable quality and after-sales support.
