Comparison of material on valve balls and seats
1.The three most common materials for balls and seats are Tungsten Carbide, Nickel Carbide, and Titanium Carbide (balls only).
Tungsten Carbide is the industry standard and for good reason;
2.Tungsten carbide has proven itself over many years of service in the field with excellent wear properties and has a cobalt binder.
3.Nickel Carbide has similar wear properties and has a nickel binder,it is best suited to corrosive and/or wet environments.
4.Titanium Carbide is the relatively “new kid on the block”. It is a highly alloyed material suitable for all environments. Titanium Carbide has the advantages of being less expensive, easier to grind, and weighs considerably less than the other two materials. However, it is best suited for balls only, not seats.
