Product Details
Product Usage:
Q361F type PN1.6-PN2.5 carbon steel fully welded ball valve is widely used in various fields. Its superior quality and high performance stability are not achieved by ordinary cast steel ball valves. The service life of all welded ball valves is far greater than Cast steel ball valves, all welded ball valves are widely used in urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other pipeline equipment.
Advantage
1. The fluid resistance of the carbon steel fully welded ball valve is small, and its resistance coefficient is equal to the pipe length of the same length.
2. The structure is simple, small in size and light in weight.
3. It is close and reliable. At present, the sealing surface material of the ball valve is widely used in plastic and has good sealing performance. It has also been widely used in vacuum systems.
4. The operation is convenient, the opening and closing is rapid, and the rotation is 90° from full opening to full closing, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When the carbon steel fully welded ball valve is fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve.
