    Abstract: A fluid control valve including a spool whose end exposable to corrosion environment is tapered to a reduced diameter and coated with corrosion resistant material. The reduced diameter facilitates fast, economical final machining and sizing of the spool without damaging the protective coating, for selective fitting within a fluid control valve body bore.

    Abstract translation: 一种流体控制阀,包括一个卷轴,其端部可暴露于腐蚀环境中,锥形到减小的直径并涂有耐腐蚀材料。 减小的直径有助于快速,经济的最终加工和阀芯尺寸,而不会损坏保护涂层,以便选择性地装配在流体控制阀体孔内。
