Application:
Perkins 1004 Phaser, 1006 Phaser, and 6.354 series diesel engines (4-cylinder and 6-cylinder configurations) . This exhaust valve controls exhaust gas flow from the combustion chamber in moderate to heavy-duty diesel applications where exhaust gas temperatures exceed 700°C. Commonly deployed in Massey Ferguson 1000, 2000, 3000, 4000, 6000, and 8000 series tractors , Cater backhoes and telehandlers, JCB wheeled loaders and telescopic handlers (CX series, 407BZX, 410BZX) , and FG Wilson generator sets powered by Perkins Phaser engines. Each 4-cylinder engine requires 4 exhaust valves; each 6-cylinder engine requires 6 exhaust valves.
Technical specifications:
Valve type: Exhaust (discharge) valve for four-stroke diesel engines
Stem diameter: 9.4 mm (0.370 inches)
Overall length: 123.3 mm (4.843 inches)
Head diameter: 37.3 mm (1.469 inches)
Seat angle: 45° precision-ground sealing face
Stem type: 1G (single-groove for split collet retention)
Tip configuration: Induction-hardened to resist wear from rocker arm contact
Weight: 0.114 kg (0.251 lbs) per valve
Material: High-alloy heat-resistant steel (European standard EN 59/SUH-4 chromium-nickel-silicon alloy)
Quantity per engine: 4 pieces for 1004 series (4-cylinder), 6 pieces for 1006/6.354 series (6-cylinder)
Material & performance features:
Manufactured from EN 59/SUH-4 chromium-nickel-silicon alloy steel providing exceptional resistance to high-temperature scaling and corrosion at continuous exhaust gas temperatures up to 750°C. The valve head undergoes solution treatment at 1,050-1,100°C followed by age-hardening to achieve 28-32 HRC hardness, maintaining structural integrity under severe thermal cycling.The stem receives gas nitriding treatment creating a 0.02-0.04 mm deep surface layer exceeding 750 HV hardness to resist scuffing during prolonged operation in dry or contaminated oil environments. The 45° seat angle is precision-machined to Ra 0.4-0.8 µm finish, ensuring positive sealing with the valve seat insert (typically 3314A009, 3314A051, or 3314A102) and preventing blow-by and compression loss. The tip is induction-hardened to 52-56 HRC to resist cupping under 900-1,100 N valve spring loads .
