1、 Advantages of high-pressure ball valves:;

When the high-pressure ball valve is closed, the sealing surface can be sealed solely by relying on the pressure of the medium, that is, the sealing surface of the valve plate can be pressed towards the other side of the valve seat to ensure the sealing of the sealing surface, which is self sealing. Most high-pressure ball valves use forced sealing, which means that when the high-pressure ball valve is closed, external force must be used to forcefully press the valve plate towards the valve seat to ensure the sealing of the sealing surface& Nbsp;

When opening the high-pressure ball valve, when the lifting height of the valve plate is equal to 1:1 times the diameter of the high-pressure ball valve, the fluid channel is completely unobstructed, but this position cannot be monitored during operation. In actual use, the vertex of the valve stem is used as a marker, that is, the position that cannot be opened, as its fully open position. To consider the phenomenon of locking due to temperature changes, it is usually necessary to open the high-pressure ball valve at the top position and then reverse it by 1/2 to 1 turn as the position for fully opening. Therefore, the fully open position of the high-pressure ball valve is determined by the position of the valve plate (i.e. stroke). The sealing surface is prone to wear and tear, which affects its service life. When opening and closing, the two sealing surfaces of the valve plate and valve seat rub and slide against each other, which can easily cause scratches and wear under the pressure of the medium, affecting the sealing performance and shortening its service life.

For a long time, the general high-pressure ball valves used in the market have generally suffered from water leakage or rusting, overcoming defects such as poor sealing and rusting. High pressure ball valves use the compensation effect of slight elastic deformation generated by the elastic valve plate to achieve good sealing effect, with significant advantages such as light opening and closing, reliable sealing, good elastic memory, and service life. It can be widely used as a regulating and intercepting device on pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, light textile, electricity, ships, metallurgy, energy systems, etc. This is where the benefits and advantages of high-pressure ball valves lie& Nbsp& Nbsp;

2、 Application of high-pressure ball valve:;

High pressure ball valves are widely used as regulating and shut-off devices in fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, light textile, electricity, ships, metallurgy, energy systems, etc& Nbsp;

3、 Characteristics of high-pressure ball valves:& Nbsp;

1. Flat bottom valve seat, no accumulation of dirt, making the seal more reliable& Nbsp& Nbsp;

2. The valve disc is wrapped in nitrile rubber as a whole, and the valve internals are made of corrosion-resistant and stainless steel and copper alloy materials, which can adapt to harsh working environments using sewage systems& Nbsp;

3. Small size, light weight, easy to install and maintain& Nbsp;

4. The valve stem adopts three O-ring seals, greatly reducing friction resistance during switching, and the switch is lightweight and leak free.
