High Pressure Ball Valve Seals Reliable

Ningbo E.H Hydraulic Co.,Ltd | Updated: Oct 20, 2017


High-pressure ball valve Advantages:

A. High pressure ball valve wide range of applications, ranging from small to several millimeters, large to a few meters, from high vacuum to high pressure can be applied.

B. Close and reliable. It has two sealing surfaces, and the current ball valve sealing surface materials widely used a variety of plastic, good sealing, can achieve complete sealing. 2-way High Pressure Ball Valve It is also widely used in vacuum systems.

C. Easy to operate, open and close quickly, from open to full off as long as the rotation of 90 °, easy to control long-distance.

D. Fluid resistance is small, the full diameter of the ball valve is basically no flow resistance.

E. High pressure ball valve structure simple, small size, light weight.

F. In full open or closed, high-pressure ball valve of the sphere and seat of the sealing surface and media isolation, 2-way High Pressure Ball Valve the media through, will not cause the valve seal surface erosion.

G. As the ball valve in the opening and closing process has a wipe, so can be used with suspended solids in the medium.

H. This kind of ball valve maintenance is convenient, the structure is simple, the seal ring is generally active, the disassembly replacement is more convenient.

High-pressure ball valve working principle: high-pressure ball valve It has a rotation of 90 degrees of action, the plug body is a sphere, there is a circular pass through the hole or channel through its axis. High-pressure ball valve in the pipeline is mainly used to cut, allocate and change the direction of the flow of the medium, it only needs to rotate 90 degrees of operation and very small rotation torque can be closed tight. The ball valve is most suitable for switch, cut-off valve use, but recent development has been designed to make it have throttle and control flow, such as V-type ball valve. High-pressure ball valve body can be a whole, 2-way High Pressure Ball Valve can also be combined. The main characteristic of high-pressure ball valve is its compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical surface often in closed state, not easily by the media erosion, easy to operate and repair, applicable to water, solvents, acids and natural gas, such as the general working medium, 2-way High Pressure Ball Valve but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, Methane and ethylene are widely used in various industries.

High-pressure ball valve came out in the 1950s, with the rapid development of science and technology, production technology and product structure of continuous improvement, in a short period of 40 years, has rapidly developed into a major valve. In the western countries of industrial developed countries, the use of high-pressure ball valve is rising year in, in China, the ball valve is widely used in petroleum refining, long-distance pipeline, chemical, papermaking, pharmaceutical, Water conservancy, electricity, municipal, steel and other industries, in the national economy occupies a pivotal position.

High-pressure ball valve is mainly used to truncate or connect the medium in the pipeline, can also be used for fluid regulation and control, wherein the hard seal V-type ball valve has a strong shearing force between the V-type ball core and the metal valve seat of the surfacing cemented carbide, 2-way High Pressure Ball Valve especially suitable for medium including fiber, tiny solid material and so on. The multi-pass ball valve can not only flexibly control the confluence, shunt and flow of the media, but also close any channel and connect the other two channels. These valves should be installed horizontally in piping.

The working principle of high-pressure ball valve:

direction, it only needs to be rotated 90 degrees of operation and very small rotation torque can be closed tightly. The ball valve is most suitable for switch, cut-off valve use, but recent development has been designed to make it have throttle and control flow, such as V-type ball valve.

The main characteristic of high-pressure ball valve is its compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical surface often in closed state, 2-way High Pressure Ball Valve not easily by the media erosion, easy to operate and repair, applicable to water, solvents, acids and natural gas, such as the general working medium, but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, Methane and ethylene are widely used in various industries. The ball valve body can be a whole, or it can be combined.

Advantages of high pressure ball valve:

1. The flow resistance is small, the whole diameter ball valve basically has no current resistance.

2. Simple structure, small size, light weight.

3. Tight and reliable. It has two sealing surfaces, and the current ball valve sealing surface materials widely used a variety of plastic, good sealing, can achieve complete sealing. It is also widely used in vacuum systems.

4. Easy to operate, open and close quickly, from open to full off as long as the rotation of 90 °, easy to control long-distance.

5. Convenient maintenance, simple structure of the ball valve, 2-way High Pressure Ball Valve sealing ring is generally active, disassembly and replacement is more convenient.

6. In open or full closed, the ball and valve seat sealing surface and media isolation, media through, will not cause the valve seal surface erosion.

7. Wide range of application, path from small to several millimeters, 2-way High Pressure Ball Valve large to a few meters, from high vacuum to high pressure can be applied.

8. As the ball valve in the opening and closing process has a wipe, so can be used with suspended solids in the medium.
