Three Panel Female Screw Ball Valve
Product overview
Three panel female screw ball valve is divided into integral one-piece, two-stage and three-stage type. Valve body casting adopts advanced technology, reasonable structure and beautiful shape. The valve seat adopts elastic sealing structure, which is reliable and easy to open and close. The valve stem adopts the bottom mounting structure with reverse sealing, and the valve stem will not be washed out when the valve chamber is abnormally pressurized. Three piece internal thread ball valve is suitable for PN1.0 ~ 6.4Mpa, working temperature - 29 ~ 180 ℃ (sealing ring is reinforced polytetrafluoroethylene) or - 29 ~ 300 ℃ (sealing ring is para polyphenylene). It is used to cut off or connect medium in pipeline. Different materials can be used in water, steam, oil, nitric acid, acetic acid and other media.
Product Features
1. The flow resistance is small, and the ball valve with full diameter has no flow resistance.
2. It has the advantages of simple structure, small volume and light weight.
3. Tight. It has two sealing surfaces, and the sealing surface material of ball valve is plastic, which has good sealing performance and can realize sealing. It has also been used in vacuum system.
4. It is easy to operate and fast to open and close. From full opening to full closing, only 90 ° rotation is needed, which is convenient for remote control.
5. Maintenance is convenient, ball valve structure is simple, seal ring is generally movable, disassembly and replacement are more convenient.
6. When the valve is fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, which will not cause erosion of the valve sealing surface when the medium passes through.
7. Wide range of applications, diameter from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied.
8. Since the ball valve can be wiped in the process of opening and closing, it can be used in the medium with suspended solid particles.
