DVU系列排污阀

 

产品介绍

Murphy DVU型系列产品为气动控制排泄阀 . 该阀门由经摩菲公司 L1200NDVOR 产品或同类液位控制阀和排泄阀控制器通过的气体控制开闭 . 该阀门为压力膜片驱动 , 气体压力工作范围为 30-70psi(207-483kpa)[ 2.07-4.83bar]. 根据不同产品型号 , 容器最大允许压力为 2000psi(13.8Mpa)[138bar] 。

该产品一个方便之处在于不用把产品从管路上卸下 , 通过产品上的六角活接就可以更换基座 。

 

产品应用

Murphy DVU系列排泄阀安装在压缩机洗涤罐上 , 用来控制洗涤罐沉淀物的排放 。

Scrubber Level System Tools

Scrubber Level Control System Emissions Calculator (.xls, 613KB)

The SLS Emissions Calculator allows you to plug in application information, such as ambient temperature, dump frequency, dump rate and supply pressure, and provides the total system emission of gas per hour.

DVU Selection Guide (.zip, 327KB)

The DVU Selection Guide selects the appropriate dump valve model for the user using a series of calculations. This calculation is obtained after the user inputs application information such as diameter of vessel, duration of dump cycle, vessel pressure and pressure at outlet of DVU.
