WESPC Exhaust Valve CH11022 for Perkins 2306 2506 2806 Series | 39mm Head Diameter 147mm Length

WESPC Exhaust Valve CH11022 is a precision-engineered component designed specifically for Perkins 2306, 2506, and 2806 series diesel engines.

This exhaust valve is engineered for Perkins 2306, 2506, and 2806 series diesel engines, which share the same 4.0 L cylinder block architecture as the earlier T4.236 and AT4.236 turbocharged family. These engines power:

• 75-400 kVA generator sets (FG Wilson P27-P55, Pramac GBW)
• High-horsepower agricultural tractors (Massey Ferguson 8200-series, Landini Legend 145)
• Combine harvesters (MF IDEAL 40)
• Mobile compressors and marine auxiliaries
• Irrigation pumps and drilling rigs

The valve drops directly into the hardened seat insert CH10732 and uses the same split-collet, spring, and rotator hardware as 1104 and 1106 derivatives.

Manufactured from 21-4N (X53CrMnNiN21-9) austenitic steel that maintains tensile strength above 750 MPa at 850°C. The head features a 1.2 mm thick Stellite 6 overlay providing 38 HRC hardness for superior hot-gas corrosion resistance.

• 21-4N alloy with 25% chromium and 9% manganese for oxidation resistance in high-temperature exhaust gas
• Stellite facing prevents guttering and enables 20,000+ hours of operation in 400 kVA gensets using low-cetane fuel
• Chrome-plated stem reduces guide wear to less than 3 µm per 1,000 hours
• Induction-hardened tip resists hammer wear from rotator caps
