Spirax DP163 diaphragm type valve series
Spirax DP series vacuum run, can be used for steam, compressed air andother gas pressure control. The downstream pressure induced by internal or external pipe pressure feedback to the pilot valve, operated by the main valve diaphragm, opening regulating valve. Even in the upstream pressure and steam load change, can accurately control the downstream pressure.
In order to meet the different needs, the DP column valve reducing valve withdifferent materials, respectively, nodular cast iron, cast steel and stainless steel. For different types of valve, the internal components of the unity of thestainless steel material, in order to facilitate the repair maintenance and replacement.
Spirax DP163 diaphragm type valve series
DP163 type pilot operated pressure relief week, stainless steel body, the main valve spool valve seat, diaphragm, valve guide, the internal spring and filterare made of stainless material. Applicable to steam and compressed air system.
The main design and application of DP163 to need to use clean steam applications, such as food, medicine, chemical industry etc.. Usually theinstallation of piping and equipment used for stainless steel, and should be installed in the high precision filter (less than 25 microns) after.
DP163G type is a soft seat, can be used for compressed air and other industrial gases, but not for oxygen.
Spirax DP163 diaphragm type valve caliber choice
And other valve, DP series valve must also correct selection, to ensure thelong-term stability of the work.
Decompression run absolutely can not by the upstream and downstream pipe diameter to determine the caliber, but must be on the basis of the downstream pressure, maximum flow to select the aperture, the system on the valve body material requirements to choose different models.
斯派莎克DP163隔膜式减压阀系列 斯派莎克DP系列减压润，可用于蒸汽、压缩空气及其它气体的压力控制。下游压力经由内部或外部的压力感应管反馈至压力导阀，由主阀隔膜操作，调节主阀的开度。即使在上游压力和蒸汽负载变化时，仍可准确的控制下游压力。
为了适应不同的需要，DP列减压阀的阀体采用了不同的材质，分别为球墨铸铁、铸钢和不锈钢。对不同型号的阀，内部组件采用统一的不锈钢材质，以方便维修保养和更换。
斯派莎克DP163隔膜式减压阀系列
DP163型导阀操作减压周，不锈钢阀体，主阀阀芯阀座、隔膜、导阀、内部弹簧及过滤网等均为不锈钢材质。适用于蒸汽和压缩空气系统。
DP163主要设计应用于需要使用洁净蒸汽的场合，如食品、医药、化学工业等。通常其安装管道及使用设备均为不锈钢，且应安装于高精度过滤器(小于25微米)之后。
DP163G型为软阀座，可用于压缩空气和其它工业气体，但不适用于氧气。
斯派莎克DP163隔膜式减压阀口径选择
与其它减压阀一样，DP系列减压阀也必须正确的选型，才能保证其长期稳定的工作。
减压润不能由上下游管径来决定其口径，而必须依据上下游压力，流量来选择其口径，由系统对阀体材质的要求来选择不同的型号。
