Product overview
Hard seal fixed ball valve is widely used in oil, gas, coal and ore mining, refining and pipeline transportation system; in chemical products, medicine and food production system; in power production system of hydropower, thermal power and nuclear power; in water supply and drainage, heating and gas supply system of urban and industrial enterprises; in drainage and irrigation system of farmland; in metallurgical production system It is an important mechanical product closely related to production and construction and people's life. The ball valve is sealed in all kinds of pipeline systems and is used to cut off or connect the medium flow, so that the medium can be transported to each designated point according to the predetermined procedure.
Product details
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.
