Product Description

Ball va e
Ball va e, ball va e in the field of Marine engineering and ship should stop va e), the standard of GB/T21465-2008 "va e terms" is defined as: opening and closing (sphere) driven by the va e stem, and around the axis of rotation movement of the va e stem.Use can also be used on regulation and control of fluid, the "V" ball va e, hard seal the v-shaped ball core of carbide surfacing with strong shear force between metal va e seat, especially suitable for fiber, micro solid material such as medium.And ball va e in the pipeline is not only more connected to the confluence of flexible control medium, shunt, and the flow switch, at the same time also can close any channel and make the other two.This va e shall generally be installed in the pipeline.Classification of ball va e, pneumatic ball va es, electric ball va es, manual ball va e.


1. The fluid resistance is small, little flow resistance full size of ball va e.

2. Simple structure, small volume, light weight.

3. Compact and reliable.It has two sealing surface, and the widely use of all kinds of plastic ball va e sealing surface of materials, good sealing, can realize completely sealed.Have been widely used in the vacuum system.

4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.

5. Easy maintenance, simple structure of ball va e, sealing ring, which generally remove replacement is more convenient.

6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause va e sealing surface erosion.

7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.

8.) wipe because of ball va es in the process of opening and closing and so can be used to bring in the medium of suspended solid particles.


High machining precision, expensive and difficult to use in high temperature, such as pipe contains impurities, easily blocked by impurities, lead to va e cannot open

According to the feature classification

1, by-pass va e, ball va e, generally for hydrostatic open, so set a by-pass va e flat first, that is filled with water on both sides;

2, air va e, water filling, exclude air taking buoy to close the va e;Drainage, complement with air, buoy from falling;

3, the pressure relief va e: open shutoff va e, eliminate between va e and plug the pressure of the water, so as not to wear sealing cover;

4, drain va e, discharge a sewage at the bottom of the ball inside the shell.

According to the classification of transmission mechanism

1, pneumatic ball va e

2, electric ball va es

3, hydraulic ball va e

4, hydraulic ball va e

5, electric hydraulic ball va es

6, turbine drive ball va e
