Application:
This exhaust valve is machined for Perkins 1004-4, 1004-4T, 1006-6,
1006-6T and 1104C-44/1104C-44T diesels (4.0–6.0 L) that power 55–70
kW generator sets, Massey Ferguson 3000/6400 tractors, JCB 3CX
back-hoe loaders and combine harvesters. It is installed in the
cylinder-head exhaust port and is designed to survive 850 °C
combustion temperature while keeping seat concentricity within 0.02
mm TIR, ensuring blow-by stays below 1 % after 12 000 h of cyclic
load.
Technical specifications:
Overall length 150 mm, head diameter 38 mm, stem diameter 9 mm,
seat face angle 45°, margin thickness 2.5 mm, stem tip
induction-hardened to 55 HRC. The valve is forged from 21-4N (UNS
S63015) austenitic stainless steel, solution-treated at 1050 °C and
age-hardened to 30 HRC at the head centre for creep resistance.
Material & performance features:
The 21-4N alloy contains 9 % Mn, 4 % Cr, 3 % Ni and 0.45 % C,
providing continuous hot strength to 850 °C and resistance to
lead/sulphur corrosion when low-grade fuels are used. Chrome
plating reduces stem wear groove depth to <0.02 mm after 6 000
h, while the roll-burnished fillet delays thermal-fatigue cracking
by 30 %.
