Welding Butterfly Valve D363H
Product Name:
Welding Butterfly Valve D363H
Description:

焊接式硬密封蝶閥 D363H :

一、產品概述 

  我廠引進能夠國外先進技術的基礎上,采用精密的J形彈性密封圈和三偏心多層次金屬硬密封結構,被廣泛用于介質溫度≤425℃的治金 、電力、石油化工、以及給排水和市政建設等工業管道上,作調節流量和載斷流體使用。該閥采用三偏心結構,閥座與碟板密封面均采用不同硬度和不銹鋼制作,具有良好的耐腐蝕性,使用壽命長,本閥軍郵雙向密封功能,產品符合國家GB/T13927-92閥門壓力試驗標準。

二、特點

1、采(cai)用三偏心蝶閥(fa)(fa)堪稱頂(ding)尖過程閥(fa)(fa)門(men),此設計(ji)使(shi)閥(fa)(fa)門(men)為高溫、高壓(ya)、防(fang)火應用中氣(qi)泡級(ji)密(mi)封的理想硬密(mi)封蝶閥(fa)(fa)。

2、由于采(cai)用焊接(jie)結(jie)構,使閥門(men)與(yu)管道平(ping)面達到永久性的(de)零泄漏。

3、此(ci)閥無法蘭(lan),對管道和(he)(he)保溫包扎帶來了很(hen)大的方便和(he)(he)美觀。
