Detailed Introduction

Soft floating seal stainless steel ball valve used for PN16⁓PN63 various piping,used to truncate or on line in the medium,choose no material,can be respectively suitable for water,steam,oil,liquefied petroleum gas,natural gas,coal gas,acetic acid,oxidizing medium,urea,and other media.

A,in all kinds of valve,ball valve flow resistance of the smallest,full bore ball valve is opened,the sphere channels,the body and connected to equal diameter and diameter,flow medium can be almost no losses.

B,ball valve can be rotated 90°seated fully open,opening and closing fast.Compared with the same specifications of the gate valve,globe valve,ball valve, small volume,light weight,easy to pipeline installation.
