AMERICAN MADE KIBBLEWHITE PRECISION MACHINE VALVES AND GUIDES ARE SIMPLY THE BEST THAT MONEY CAN BUY. WHEN USED IN CONJUNCTION WITH THESE MANGANESE-BRONZE GUIDES AND PROPERLY INSTALLED AND FINISHED THE END RESULT IS TIGHTER THAN FACTORY TOLERANCES WHICH IN TURN MEANS LONGER LIFE, LESS FRICTION AND QUIETER RUNNING. GUIDES SUPPLIED ARE THE ‘S’ TYPE WHICH CAN BE USED WITH OR WITHOUT SEALS AT YOUR DISCRETION.

FROM KIBBLEWHITE All KPMI Black Diamond™ stainless steel valves are impregnated by a special German process to a depth of .002”, with a surface build up of .0002”. This “Black Diamond®” process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating. Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. Black Diamond® Valves are light, strong, one piece forgings with profiles that provide excellent flow characteristics.
