The KPMI System

KPMI Valves

• White Diamond®: CNC machined from one-piece forgings of EV8 Stainless Steel or Inconel-751. Electroplated with a 360º anode, to produce an even coat of the highest grade hard chrome finish.
• Black Diamond®: CNC machined from one-piece forgings of EV8 Stainless Steel. Black Diamond® proprietary multi-stage process reduces friction, and provides superior resistance to corrosion and wear.
• Tensilite®: CNC machined from one-piece forgings of 6AL4V or 6-2-4-2 titanium alloy. Finished with a CrN PVD coating that has a low coefficient of friction, and is impact, abrasion, and corrosion resistant.

KPMI Valve Seats

• Powdered Metal Seats: Have exceptional thermal qualities, wear resistance and resistance to micro-welding. This material resists corrosion and burning, and is compatible with all types of fuel blends.
• Nickel Aluminum Bronze Seats: The product of a two year KPMI R&D effort, this proprietary bronze alloy is designed specifically for use with titanium valves in high performance applications.

KPMI Guides

• C630 Bronze Guides: Tough and wear resistant with excellent thermal qualities. This bronze alloy allows for tighter clearances than other materials. Creating better valve and seat sealing, as well as superior oil control.
• Cast Iron Guides: KPMI R&D has produced a proprietary cast iron blend that thrives in the tough operating conditions of today's engine. KPMI's cast iron provides excellent wear resistance and a superior guide bore finish that is easy on valve stems.

KPMI Springs

• Advanced Spring Design: Springs are engineered for each specific application using proprietary spring design, simulation, and analysis software.
• Premium Ground Chrome Silicon Wire: To insure maximum spring life, springs are heat treated, shot peened and X-rayed at regular intervals to check for inclusions.

KPMI Retainers

• Heat Treated Steel Retainers: KPMI's proprietary heat treatment process creates a hard outer shell with a non-brittle core, resisting wear and maximizing toughness.
• Titanium Retainers: To further reduce reciprocating mass, KPMI offers titanium retainers as an alternative to steel.
• High Performance Coating: CrN coating for high performance applications, to decrease friction and improve wear. Available for any application on request
• Custom Retainers Available: KPMI is ready to design a custom retainer to your specifications.

KPMI Seals

• High Temperature: KPMI Viton® seals operate at a higher temperature than other seal materials.

KPMI Tappets

• Solid Construction: Machined from aerospace quality solid steel bar stock.
• Proprietary Heat Treatment Process: Creates a hard outer shell with a non-brittle core, resisting wear and maximizing toughness
• High Performance Coating: CrN coating for high performance applications, to decrease friction and improve wear. Available for any application on request
• Custom Tappets Available: Send KPMI your requirements so we can develop your next tappet

KPMI Keepers

• Wide Variety of Styles: KPMI offers radius bead, triple radius bead, and square bead style keepers.
• High Tensile Heat Treated Steel: Forged or single point machined

KPMI Valve Adjustment Shims

• Heat Treated Steel: Ground and lapped to precise heights
