Application:
3142H111 is the inlet valve for 3-cylinder Perkins 1103D-33T, 1103D-33TA and 4-cylinder 1104D-44 / 1104D-44T diesels (3.3–4.4 L) that power JCB 3CX compact back-hoes, 45 kVA “Vista A” generators, MF 1700-series tractors and mini-excavators. It is designed to maintain volumetric efficiency >92 % at 2 800 min⁻¹ while meeting EU Stage IIIA / EPA Tier 4-final smoke limits.
Technical specifications:
Overall length 114 mm, head diameter 38 mm, stem diameter 9 mm, seat angle 30 °, margin thickness 2.2 mm, stem tip induction-hardened to 52 HRC. The valve is forged from 21-4N austenitic stainless steel, solution-treated at 1050 °C and age-hardened to 28 HRC at the head centre for creep resistance at 800 °C.
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 %.
