Stainless Steel Flange Ball Valve Installation Steps And Advantages

Introduction Of Installation Steps Of Stainless Steel Flanged Ball Valve

1. When the valve is hoisted, the rope should not be tied to the handwheel or valve stem, so as not to damage these parts, it should be tied to the flange.

2. Before installation, the valve should be checked to check the specifications and models to identify whether there is any damage, especially for the valve stem. Turn it a few times to see if it is skewed, because during transportation, the valve stem is most likely to be skewed. Also remove debris from the valve.

3. When installing the stainless steel flanged ball valves, pay attention to tightening the bolts symmetrically and evenly. The valve flange and the pipe flange must be parallel with a reasonable gap to prevent the valve from generating excessive pressure or even cracking. Special attention should be paid to brittle materials and valves with low strength. Valves that must be welded to the pipe should be spot welded first, then the closing parts should be fully opened, and then welded to death.

4. When installing the screw valve, the sealing packing should be wrapped on the pipe thread, and do not get into the valve, so as not to accumulate in the valve and affect the flow of the medium.

5. The pipeline connected to the flanged ball valve must be cleaned. Compressed air can be used to blow away mud sand, iron oxide filings, welding slag and other debris. These debris not only easily scratch the sealing surface of the valve, but also block the small valve and make it invalid.

Advantages Of Stainless Steel Flanged Ball Valve

1. The opening and closing is convenient and quick, labor-saving, small fluid resistance, and can be operated frequently.

2. Simple structure, small size and light weight.

3. The mud can be transported, and the liquid accumulation at the pipe mouth is the least.

4. Good adjustment performance with professional flanged ball valve manufacturers.

5. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.

6. Tight and reliable. It has two sealing surfaces, and various plastics are widely used for the sealing surface materials of the ball valve at present, which has good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.

7. Easy to operate, quick to open and close, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
