Shacman
| Attribute | Specification |
|---|---|
| OEM Number | DZ97189716021 |
| Cross Reference | DZ97189716022 (mirror variant or different configuration), WG9000360522 (Sinotruk equivalent) |
| Valve Type | 2-Position, 3-Way (2/3) Normally Closed (NC) |
| Operating Mode | Electrically actuated; opens when energized (12V/24V DC) |
| Voltage Rating | 24V DC (Standard for heavy-duty trucks) |
| Working Medium | Clean, dry compressed air (oil-free) |
| Inlet/Outlet Ports | G1/4" or M10x1.0 threaded ports (ISO standard) |
| Material | - Body: Aluminum alloy or steel - Internal components: Brass, stainless steel - Seals: NBR (Nitrile) or Viton® O-rings |
| Housing Material | Aluminum die-cast or steel with ABS plastic cover (depending on model) |
| Weight | Approx. 0.35 kg to 2.0 kg (varies by manufacturer and packaging) |
| Protection Rating | IP65 to IP67 (dust-tight and protected against water jets) |
| Operating Temperature Range | -40°C to +85°C |
| Response Time | < 100 ms (fast switching for precise brake control) |
| Compliance Standards | GB/T, ISO 6953, ECE R121 (for engine braking systems), RoHS |
| Warranty | Typically 3 months to 1 year (depends on supplier quality) |

Confirm Exact Compatibility Before Purchase
Match VIN, model year, engine type, and existing valve label.
Not all “compatible” valves have identical performance characteristics.
Professional Installation Recommended
Involves both electrical wiring and pneumatic connections.
Best handled by trained technicians familiar with air brake and engine brake systems.
Disconnect Battery Before Work
Remove the negative terminal to avoid short circuits or accidental activation.
Inspect Air Lines and Filters
Ensure upstream air is clean and dry.
Replace clogged filters or damaged hoses before installation.
Use Proper Thread Sealant
Apply PTFE tape or anaerobic sealant on threaded pneumatic ports.
Avoid over-tightening — can crack aluminum body.
Check Electrical Connector
Verify pin alignment and locking mechanism.
Moisture ingress can cause intermittent faults or coil burnout.
Test Functionality After Installation
Turn ignition ON and press exhaust brake switch.
Listen for audible click from valve.
Confirm that exhaust brake engages (audible change in engine sound).
Avoid Contamination During Service
Keep ports covered until ready to connect.
Dirt or moisture inside the valve can cause sticking or failure.
Do Not Exceed Operating Limits
Operate only within specified voltage (24V) and air pressure (typically ≤ 10 bar).
Overvoltage or overpressure leads to premature failure.
Include in Routine Maintenance Checks
Inspect every 10,000 km or during scheduled PM.
Check for leaks, corrosion, loose wires, or sluggish response.
Replace Entire Unit if Damaged
This is a sealed unit — non-serviceable.
Attempting repair voids warranty and compromises safety.
