It’s manufactured from a practically indestructible material—a powdered metal, high-speed tool steel—like the tool steel used in drill bits and cutting tools—with a vanadium carbide content and a red hardness high enough to make it almost invulnerable to wear. All of its surfaces are ground surfaces.
The Veloci-T is engineered for positive shutoff and optimum flow under the check ring, providing consistent results with a wide variety of different molding materials. Company sources say the product carries a slight price premium.—CK
