DZ97259090030
Shacman
| Attribute | Specification |
|---|---|
| OEM Number | DZ97259090030 |
| Alternative Names | Electric Parking Brake Valve, E-Park Valve, Solenoid-Controlled Brake Release Valve |
| Operating Voltage | 24V DC (Standard truck electrical system) |
| Control Method | Electrical signal from driver’s switch → activates internal solenoids to control air flow |
| Working Medium | Compressed Air (clean, dry, oil-free) |
| Valve Function | - Applies air to exhaust side of spring brake chamber (apply parking brake) - Releases air to apply spring force (brake engaged) - Reverses airflow when "release" command is given |
| Valve Type | 3-position, 2-solenoid pilot-operated directional control valve |
| Port Size | Typically G1/4" or G3/8" threaded ports (ISO 1502 standard) |
| Material | Die-cast aluminum alloy body; corrosion-resistant internal components |
| Seals | Nitrile rubber (NBR) or Viton® O-rings for long-term sealing performance |
| Protection Rating | IP65 to IP67 (dust-tight and protected against water jets) |
| Operating Temperature | -40°C to +85°C |
| Compliance Standards | GB12676, ISO 15365, ECE R13 (Braking Regulations), RoHS |
| Warranty | Typically 6 to 12 months (varies by supplier) |

Verify Compatibility Before Purchase
Confirm:
Exact truck model and year
Presence of electronic parking brake system
VIN and existing valve label photo if possible
Professional Installation Required
Involves both pneumatic plumbing and electrical wiring.
Must be performed by certified technicians familiar with air brake systems.
Fully Depressurize System Before Work
Release all compressed air from the reservoir tanks via drain valves.
Never disconnect lines under pressure — risk of injury or damage.
Disconnect Battery Negative Terminal
Prevents accidental activation during installation.
Protects control circuits from voltage spikes.
Inspect Air Lines and Connectors
Replace cracked, swollen, or aged hoses.
Clean metal debris or sludge from old lines before connecting new valve.
Use Proper Thread Sealant
Apply PTFE tape or anaerobic pipe sealant on threaded pneumatic connections.
Avoid over-tightening — can crack housing or strip threads.
Check Electrical Connector Alignment
Ensure pins are not bent and locking clip engages fully.
Moisture ingress can cause intermittent faults.
Test for Leaks After Installation
Recharge the air system and bring to full pressure (~8–10 bar).
Use soapy water to inspect all pneumatic joints for bubbles.
Perform Full Functional Test
Press “Apply” button — should hear air exhaust and feel brake engage.
Press “Release” button — must only work when vehicle is stationary (safety interlock).
Verify warning light on dashboard turns off after release.
Do Not Modify or Disassemble
This unit is non-serviceable — tampering voids warranty and compromises safety.
Include in Routine Brake Inspections
Check every 10,000 km or during PM service.
Listen for unusual hissing sounds or delayed response.
