Designed for Perkins 1104D-44T, 1106D-70TA, 1106A-70TA, 1106C-E70TA, and 1106D-E70TA diesel engines in both 4-cylinder and 6-cylinder configurations. This exhaust valve manages exhaust gas flow from the combustion chamber in moderate to heavy-duty diesel applications where exhaust temperatures exceed 700°C.
Common Equipment Applications
Massey Ferguson 5000 and 6000 series tractors
JCB construction equipment
Cater 320D2 excavators
FG Wilson generator sets
Hino 500 series trucks
Quantity Requirements: Each 4-cylinder engine requires 4 exhaust valves; each 6-cylinder engine requires 6 exhaust valves.

Material & Performance Features
Manufactured from premium high-chromium stainless steel forging containing 12-15% Cr, 1.0-1.5% C, with additions of Mo and N for enhanced high-temperature strength and corrosion resistance.
Valve head undergoes solution treatment at 1,150°C followed by age-hardening to achieve 30-35 HRC hardness
Maintains structural integrity at continuous exhaust gas temperatures up to 750°C
Stem receives advanced gas nitriding creating 0.03-0.05 mm deep diffusion layer exceeding 800 HV hardness
45° seat angle precision-machined to Ra 0.4-0.8 µm finish for positive sealing
Tip features induction hardening to 55-60 HRC to resist cupping under 1,200+ N valve spring loads
