德國FESTO方向控制閥產品優勢介紹:
1.產品種類繁多
2.控制精度高
方向控制閥屬于執行元件之一,根據不同的控制方式能夠分為了電磁閥,氣控閥,人控閥等,其中電磁閥還能夠分為了單和雙電控閥兩種,無論是哪種設備,該品牌的產品控制精度都是趕*,各類控制閥塊設計能夠符合流體系統標準參數設計,很多客戶之所以優先考慮該品牌設備也是因為festo費斯托的品牌優勢明顯,對于他們來說,選擇一款合適的控制閥塊誠然也是十分重要的,它將直接影響了流體系統各階段的控制效果。
3.產品細節優化到位
方向控(kong)(kong)制(zhi)閥(fa)以(yi)及其他的(de)執(zhi)行元(yuan)件(jian)都(dou)有(you)著多個(ge)部分(fen)(fen)組成,每(mei)一(yi)個(ge)單(dan)(dan)元(yuan)都(dou)是獨(du)立設計,但(dan)是液(ye)控(kong)(kong)單(dan)(dan)元(yuan)還能(neng)夠(gou)細分(fen)(fen)為調速(su)閥(fa)控(kong)(kong)制(zhi)單(dan)(dan)元(yuan)和調速(su)單(dan)(dan)元(yuan),具(ju)體(ti)(ti)能(neng)夠(gou)細分(fen)(fen)化到每(mei)個(ge)零(ling)部件(jian),同(tong)(tong)(tong)樣的(de),零(ling)部件(jian)的(de)質量好壞直接(jie)影響了產品使用效果,festo費斯托(tuo)(tuo)控(kong)(kong)制(zhi)閥(fa)不(bu)同(tong)(tong)(tong)的(de)閥(fa)體(ti)(ti)適(shi)配性不(bu)同(tong)(tong)(tong),能(neng)夠(gou)應用的(de)領域(yu)也是不(bu)盡相同(tong)(tong)(tong),大家要考慮實際到使用環(huan)境。但(dan)是從(cong)細節處理上來看,festo費斯托(tuo)(tuo)品牌(pai)是沒有(you)問題的(de),而且多年質檢也從(cong)來出過紕漏(lou)。
