Ball Valve

Ball valve uses a ball with circular hole as opening and closing device, ball rotate around center line of valve body with stem, so as to open and close valve.

I.series of ball valve

Ball valve has two types of structure, which of split body and three-piece body. Besides small fluid resistance, fast opening and closing, simple structure, has the following features:

1.Ball valve with FEP lining has high chemical stability, can be applicable for any strong corrosive medium except molten alkali metal and fluorine

2.The structure of full bore, floating ball can close under full pressure without leakage, is also convenient for pipeline pigging and pipeline maintenance.

3.Compact structure and smallest space of valve cavity reduced medium retention. In addition, special molding process make the sealing face has good sealing, plus the PTFE packing, the valve can realize no leakage.

4.Structure of split body and three-piece body could be applicable for pipeline system of any requirements and services, in which valve of three-piece body allows main valve body to separate from valve body of two sides; can realize quick replacement and maintenance on site.

II.Design specification

As per standard of GB 12237/API 608/API 6D

III.Drive mode

Manual, worm gear, pneumatic, hydraulic
