DZ91189180014
Shacman
| Attribute | Description |
|---|---|
| Product Name | Exhaust Brake Assembly / Exhaust Butterfly Valve |
| Common Name | Engine Brake Valve, Exhaust Retarder, Backpressure Valve |
| Function | Generates engine backpressure to assist vehicle deceleration; reduces reliance on friction brakes |
| Valve Type | Rotary butterfly valve with full-flow open and near-closed positions |
| Actuation Method | Pneumatically controlled via solenoid valve and air cylinder |
| Material – Valve Body | High-temperature resistant cast iron or alloy steel |
| Material – Shaft & Disc | Heat-treated stainless steel or nickel-based alloy for thermal stability |
| Operating Environment | Installed in exhaust system downstream of turbocharger; exposed to temperatures up to 650°C (1200°F) |
| Sealing Type | High-temp metal-to-metal seal with optional graphite gasket interface |
| Parameter | Specification |
|---|---|
| Part Number (OEM) | DZ91189180014 |
| Valve Diameter | Typically 115 mm (may vary slightly based on variant) |
| Control System | Air-operated (compressed air at 6–8 bar / 87–116 psi) |
| Drive Mechanism | Double-acting pneumatic actuator (air cylinder) |
| Response Time | < 1 second from signal input to full closure |
| Max Operating Temperature | Up to 650°C continuous; peak up to 700°C (short-term) |
| Backpressure Generated | ~4–6 bar (depending on engine speed and load) |
| Mounting Style | Flanged or clamp-on connection between turbo outlet and exhaust pipe |
| Durability | Rated for over 500,000 cycles under normal working conditions |
| Design Standard | Meets SHACMAN OE specifications for Delong series platforms |
