ST aluminum bronze ball valve using jacket structure, the main alloy elements for nickel, iron and manganese;
In practice, in order to meet different needs, a certain amount of manganese, iron, nickel, zinc and other elements are often added to aluminum bronze to change the properties of the alloy.
With excellent corrosion resistance, it is an important material for ship propellers and underwater fasteners, and has been widely used in seawater desalination engineering.
Structural Features:
1、ST aluminum bronze ball valve has sort seal and hard seal sturcture
2、There are two forms,full diameter and half diameter
3、have fire prevetion,anti-static device
4、The stem is designed to prevent blowout from the valve body due to improper operation
5、Can support a variety of driving device connection disk.The driving device includes:handle,worm wheel,electric,gas-liquid linkage,elecrtro-hydraulic linkage,etc
6、Buried design,buried installation of the valve,vave stem according to the needs of the project extension,so as to operation on the ground.
