| Presetting Using the flow coefficient information the valve can be pre-set to given Cv value Operate counter clockwise until the required set position is aligned with the fixed stop. Without changing the stem position  remove the hand wheel and refit the memory stop aligned adjacent to the fixed stoop on the clockwise side when viewed from above. Refit the hand wheel retaining screw. The valve can be closed and re-opened to the pre-set position. De-alloying corrosion, known as "Dezincification" was effectively eradicated from valve products in the 1950's today. However, this problem has returned with the increased use of high-zinc alloys(commonly referred to as ' Yellow Brass')in forged and cast valves typically produced outside the United States. Dezincification selectively removes zinc from the alloy, leaving behind a porous, copper-rich structure that has little mechanical strength. The physical attributes of an in-service valve with Dezincification includes a white powdery substance or mineral stains on its exterior surface As standard WORLD bronze/brass balancing valves are made to be "Dezincification Resistant,"which is a seal of quality and longevity. |
