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

焊接式硬密封蝶阀 D363H :

一、产品概述 

  我厂引进能够国外先进技术的基础上,采用精密的J形弹性密封圈和三偏心多层次金属硬密封结构,被广泛用于介质温度≤425℃的治金 、电力、石油化工、以及给排水和市政建设等工业管道上,作调节流量和载断流体使用。该阀采用三偏心结构,阀座与碟板密封面均采用不同硬度和不锈钢制作,具有良好的耐腐蚀性,使用寿命长,本阀军邮双向密封功能,产品符合国家GB/T13927-92阀门压力试验标准。

二、特点

1、采用三偏心蝶阀堪称顶尖过程阀门,此设计使阀门为高温、高压、防火应用中气泡级密封的理想硬密封蝶阀。

2、由于采用焊接结构,使阀门与管道平面达到永久性的零泄漏。

3、此阀无法兰,对管道和保温包扎带来了很大的方便和美观。
