　　RFS气动黄铜丝口闸阀RFS yellow wire port pneumatic valve：


RFS pneumatic brass wire port valve can only be fully open and fully closed, and is not suitable for adjusting the throttle. Brass wire port valve has two sealing surface, the two most commonly used sealing surfaces wedge gate valves forming wedge, wedge angle with the valve parameters vary, usually 5o. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce small quantities of deformation gate in order to improve its process, to make up the sealing surface angle deviations arising during processing, this gate board called the flexible gate.
RFS气动黄铜丝口闸阀只能作全开和全关，不适合作调节和节流。黄铜丝口闸阀有两个密封面，最常用的楔式闸板阀的两个密封面形成楔形，楔形角随阀门参数而异，通常为5o。楔式闸阀的闸板可以做成一个整体，叫做刚性闸板；也可以做成能产生微量变形的闸板，以改善其工艺性，弥补密封面角度在加工过程中产生的偏差，这种闸板叫做弹性闸板。

RFS气动黄铜丝口闸阀适用工况：
公称压力：1.6MPa
工作介质：水、油、汽
工作温度：t≤100℃
管螺纹符合ISO228标准
RFS pneumatic valve brass wire mouth conditions apply:
Nominal pressure: 1.6MPa
Working medium: water, oil, gas
Working temperature: t≤100 ℃
Standard Pipe thread to ISO228

RFS气动黄铜丝口闸阀具有以下优点；
1、流体阻力小，密封面受介质的冲刷和侵蚀小。
2、开闭较省力。
3、介质流向不受限制，不扰流、不降低压力。
4、形体简单，结构长度短，制造工艺性好，适用范围广。
