# 气源处理附件 - 闭锁阀

> 闭锁阀，可达到150 psi是一款单作用弹簧复位的2/2 阀 。该装置要求先导气动信号打开。当先导信号消失时, 内部弹簧会关闭闭锁阀, 圆形罩锁紧。

所属技术：气动技术

## 系列介绍

截止阀是单作用弹簧复位2/2阀，采用配合形式。该装置需要打开气动导阀信号，允许空气，气体或液体自由流动。只要存在导频信号，设备将保持打开状态。当导向信号被移除时，内部弹簧将关闭截止阀，气泡密封。 截止阀可用油，额定压力为150 PSI。这些装置具有两个主要设计用途：（1）在关闭过程期间或在供应压力损失期间防止不希望的重力引起的气缸运动;以及（2）通过在气缸的每个端部处使用截止阀来冻结气缸位置。这些装置通常满足应用需求，例如工具或工件保护，水平分度或检查停止。 •端口尺寸：1/8“，1/4”，3/8“，1/2” •工作压力：0至150 psi（或0至10.3 bar） •工作温度：5°至140°F（或-15°至60°C） •主体材质：锌合金 •允许流体惰性气体，50μm过滤 •最大工作频率：10 Hz •机械寿命：1000万
