Tungsten Carbide Valve Ball Advantages (1/2)

Tungsten carbide valve ball uses ball as device for start and stop, which has many functions, such as cutting, distributing and changing the flow direction of the media, specially designed can regulate the flow. From the design of the ball valve, compared with conventional valve, it has many advantages, such as simple structure, excellent sealing property, light in weight, low consumption, small setting size, small volume in a range of certain nominal diameter, small driving moment, easily to start or stop quickly, which becomes the rapidest developing valve in recent years gradually. Tungsten carbide ball combines the advantages of tungsten carbide (high hardness, high strength, high melting point, excellent chemical stability and wear and corrosion resistance) with ball valve can be suitable to the strict conditions of many industries today.

The advantages of tungsten carbide ball valve are given as follow:

1. It has the lowest flow resistance theoretically (Flow resistance refers to the steady state airflow, sound-absorbing material is applied to the sample and the pressure difference across the air flow through the sample line speed ratio.);

2. It has excellent chemical stability and wear or corrosion resistance, which can be contact with most of liquid and some media with corrosive property;

3. It has excellent sealing property at high temperature and high pressure (Nominal pressure from vacuum to 42MPa);

4. Tungsten carbide valve ball using ball as the device for start and stop so that it affected by friction slightly and can be starting or stopping quickly (in a range of 0.05-0.1s), and has small operating impact. In addition, spherical device can endure the higher pressure differential when it close and can achieve automatic position;
