The QZ11F type ball valve is mainly used to cut off or connect the suitable medium in the pipeline. The selection of different materials can be applied to various suitable medium, such as water, steam, oil, nitric acid and acetic acid, etc.
The characteristics of a, two ball valve products:
*. The threaded ball valve and welded connections into the integral (two piece), one segment and three segment type.
It adopts advanced technology and imported from Taiwan. The valve body casting, reasonable structure and beautiful shape. The valve seat adopts the elastic seal structure, the seal is reliable, and the opening and closing are easy.
*. Stem seal downloading inverted structure, abnormal pressure of the valve chamber, the stem will not be out.
Two. To type three ball valve connection form another butt (BW) socket (SW), and can stand with the international standard ISO platform and locking device.
It can be set to 90 degrees. The switch positioning mechanism, driving according to the lock to prevent incorrect operation mode: manual, electric, pneumatic.
