產(chǎn)品特點:
1.本產(chǎn)品所有部件均為鍛件
2.采用下裝式閥桿,設置倒密封結構,確保填料處可靠密封及防止閥桿脫出。
3.采用鑲嵌式閥座。閥座背后設置O型圈,確保介質(zhì)不外漏。 Features 1.All the components are forged ones.
2.Lower-loading Stem and backward sealing construction have been setup for positive sealing at stuffing position and backing-out protecting of the handle.
3.Interbedded valve seat is applied on whose bace RO-ring is also mounted for avoiding the leakage of medium.
