                    PENTAFITE是一种以金属为基质、内部均匀散布固体润滑剂的混合物，其主要用于生产Penta已获专利的金属阀座。这种材料通过类似于烧结的制造工
                    艺由单一组分的细粉末生产获得，该材料可用于生产金属球阀阀座嵌件的金属环，并且能够适应高温、高压或压力/温度高于聚合物材料耐受极限的应用
                    场合。
                    PENTAFITE  is  a  compound  with  metallic  matrix  and  fine  dispersion  of  solid  lubricant  inside  used  for  the  production  of  the  unique
                    Penta  patented  metallic  seats.  It  is  obtained  by  a  manufacturing  process  similar  to  sintering  with  which,  starting  from  fine  powders  of  the
                    single component, is possible to produce the metallic rings that form the seat insert for our metal seated ball valves for services with high
                    temperature, high pressure or with combination pressure/temperature higher than tolerable limits for polymeric material.

                                                                                               SCRAPER RINGS






















                    刮环是安插在Pentafite阀座内外两侧的2个环。
                    该刮环的作用如下：
                    • 在阀门工作期间清洁阀球表面。
                    • 保护阀座免受液体中固体成分磨损。
                    • 避免在阀座和球体表面之间卡入固体，以免造成阀门堵塞。
                    • 减少可能填满腔体的污垢量。
                    The scrapers are 2 rings inserted one inside and one outside the Pentafite seats.
                    The scraper rings have to:
                    • Clean ball surface during valve operation.
                    • Protect the seats from abrasion by fluid solid content.
                    • Avoid wedging in of solids between seat and ball surface cause of valve blocking.
                    • Reduce dirt that can fill body cavities.
