MIL-DTL-32632涵盖了膨胀、低扭矩、无滞后设计的流量控制阀，采用多段虹彩阀座盘结构，用于海军舰载水、油和天然气服务。这些阀门用于液体和气体的精确流量控制，并允许在完全打开时自由流动。

MIL-DTL-32632 covers flow control valves of dilating, low torque, hysteresis-free design employing multiple-segment irising seat-disks construction for naval shipboard water, oil, and gas services. These valves are for precise flow control of liquids and gases and allow unconstrained flow when fully open.
