Sizes ¹/₂" – 2" (15 - 50mm)

　　系列152A工艺蒸汽压力调节阀适用于为减少压力变化和在不会明显减少压降的情况下维护最大可能流量提供高度的敏感反应。这些调节阀的理想应用场合如油管线，检测装置，高压锅，蒸汽保温餐桌，蒸汽熨斗，单散热器，硫化器，杀菌器和生产线。这个系列152A特点在于其敏感的调节功能，避免由于临界流量需求可能产生的任何压力波动。
　　Series 152A Process Steam Pressure Regulators are designed to offer highly sensitive response to reduced pressure changes and maintain fullest possible volume without appreciable reduced pressure drop. These regulators are ideal for use on applications such as oil lines, testing fixtures, autoclaves, steam tables, steam irons, single radiators, vulcanizers, sterilizers and process lines. The series 152A features a sensitivity adjuster to eliminate any vibrating condition that may arise from critical flow requirements.
