Ball valves are mainly used in pipelines to cut off, distribute, and change the direction of medium flow. The ball valve designed with a V-shaped opening also has good flow regulation function.

The opening and closing component of a ball valve is a sphere, which rotates 90 degrees around the axis of the valve stem to achieve the purpose of opening and closing. Ball valves have the advantages of low flow resistance, simple structure, small volume, light weight, good sealing, convenient operation, quick opening and closing, and easy remote control. Ball valves are most suitable for use as switches and shut-off valves.

1. Nominal pressure or pressure level: PN1.0-42.0MPa, ANSI Class 150-2500, JIS10-63K;

2. Nominal diameter or diameter: DN6-900, NPS 1/4-36;

3. Connection methods: flange, butt welding, threading, socket welding, etc;

4. Applicable temperature: -196 ℃~540 ℃;

5. Driving methods: manual, worm gear and worm drive, pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage;

6. Valve body materials: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. By selecting different materials, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc.

Advantages

1. Ball valves have very low flow resistance.

2. Ball valves can be reliably applied in corrosive media and low boiling liquids.

3. Ball valves can achieve complete sealing over a wide range of pressure and temperature.

4. The ball valve can achieve rapid opening and closing to ensure its use in the automation system of the test bench.

5. The spherical closure can automatically locate at the boundary position.

6. The working medium is reliably sealed on both sides.

7. When fully open and fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, so the medium passing through the ball valve at high speed will not cause erosion of the sealing surface.

8. The structure of ball valves is compact and lightweight. It can be considered as the most reasonable valve structure for low-temperature medium systems.

9. The valve body of the ball valve is symmetrical, especially the welded valve body structure, which can withstand the stress from the pipeline well.

10. The closing component can withstand the high pressure difference when closed.

11. The ball valve with a fully welded valve body can be directly buried underground to prevent erosion of the valve's internal components. The maximum service life can reach 30 years, making it the most ideal valve for oil and natural gas pipelines.
