Product Features

• Structure: An integrated assembly consisting of a high-temperature cast iron exhaust elbow, a precision-machined valve plate, and a hydraulic actuation cylinder. The cylinder features a corrosion-resistant coating for durability.

• Performance: The cast iron elbow withstands exhaust temperatures up to 950°C, while the hydraulic cylinder delivers fast, reliable actuation of the valve plate to create engine backpressure for auxiliary braking.

• Design: Direct-fit replacement with pre-installed sealing gaskets and mounting hardware, ensuring quick installation and compatibility with the original exhaust system.

Core Function

• When activated, the hydraulic cylinder closes the valve plate to block the exhaust passage, creating backpressure in the engine cylinders to slow the vehicle, reducing reliance on the service brakes.

• Enhances driving safety during downhill or heavy-load deceleration by providing consistent auxiliary braking force, reducing brake wear and overheating.

• Maintains unobstructed exhaust gas flow when deactivated, ensuring optimal engine performance and fuel efficiency.

Frequently Asked Questions – Exhaust Brake Valve With Cylinder-MC13 202V15201-6227

Q1: Is this exhaust brake valve an original OEM part or an aftermarket replacement?

This is an OEM-specification aftermarket part manufactured to match the exact dimensions, materials, and performance standards of the original SINOTRUK 202V15201-6227. It passes the same pressure and cycling tests as the factory-installed unit.

Q2: How do I know if this exhaust brake valve fits my truck?

If your vehicle is equipped with a SINOTRUK MC13 engine and the existing part number on your current valve reads 202V15201-6227, this is a direct bolt-on replacement. If you are unsure, send us your VIN or engine nameplate photo and our engineers will confirm compatibility within 24 hours.

Q3: What causes an exhaust brake valve to fail, and how can I extend its life?

Common failure modes include carbon buildup on the valve plate, worn cylinder seals from moisture in the air supply, and heat fatigue from prolonged high-RPM braking. Regular air dryer maintenance, periodic carbon cleaning every 100,000 km, and avoiding sustained full-throttle braking above 2,200 RPM will significantly extend service life.

Q4: Can I order just the pneumatic cylinder or just the valve body separately?

The 202V15201-6227 is supplied as a complete assembly (valve body + cylinder). This ensures proper calibration and eliminates the risk of mismatched components. If you need individual sub-components, contact our team for availability.

Q5: What is the warranty policy for this exhaust brake valve?

We provide a 12-month or 100,000 km warranty (whichever comes first) against manufacturing defects. Claims are processed with photographic evidence and resolved within 7 business days.
