TECHNICAL FEATURES
GENERAL REMARKS                Our products currently available to fulfill the strict requirements of designers and users.
                The range includes Wafer Style and Lug Style Butterfly Valves in the size range of DNS0-DN600 which can be installed with pneumatic and electric actuators. 
                To meet the specification requirements of DIN 3230 has ho leakage， Butterfly Valves with a conentric disc must have a special design emphasis on the seal tolerance between the disc and the Liner.
                The primary seal is achieved by means of the interference between the disc and the surface of the liner， particulaly in the area of the shaft locations， seals in the Liner collours and on the shaft ensure supplementary security.技術(shù)特點(diǎn)
總論        我們的產(chǎn)品範(fàn)圍包括目前現(xiàn)有的一些理論做出的產(chǎn)品，將盡可能地滿足設(shè)計(jì)師和使用設(shè)的利益。蝶閥樣式有對夾式彈性和對夾凸耳式兩類，尺寸範(fàn)圍在DN50至DN600之間，可搭配氣動(dòng)或電動(dòng)執(zhí)行器。
        爲(wèi)了使蝶閥能達(dá)到零泄漏，這就要求我們要有獨(dú)特的設(shè)計(jì)。獨(dú)特之處便是閥體和閥板之間的密封圈。
      密封圈夾在閥體和閥板之間，確保可靠的密封性能和安全。
