What is sanitary ball valves？

Ball valve is actually a kind of valve, which is another form of control switch. Ball valve can be divided into sanitary ball valve and ordinary ball valve. Because sanitary ball valve has many improvements and more advantages compared with ordinary ball valve, it is commonly used in the market now. Sanitary ball valve in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium. It can be closed tightly with only 90 degree rotation and a small rotating torque. Since the sanitary ball valve is widely used, it is necessary to know some knowledge about it.

Detailed introduction of the sanitary ball valves

Sanitary ball valve is made of stainless steel 304SS or 316, standard electronic polishing, smooth surface to ensure clean, no media storage area, no potential pollution, can meet the special requirements of various media in food and biopharmaceutical fields. Stainless Steel sanitary ball valves are smooth, seamless, and automatically empty. The process fluid channel is also very suitable for the on-site cleaning of steam treads. The connection mode of sanitary valves can be in the form of thread, flange, welding, clamp and sleeve according to the general situation of the project. Sanitary ball valve is widely used in food, wine, beverage, dairy products, fine chemical pharmaceutical and bioengineering industries.

 

What is the structure of the sanitary ball valves?

The sanitary ball valve has good sealing performance, but the load of the working medium on the ball is transferred to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium, and the ball of the sanitary ball valve may deviate under the impact of high pressure. This structure is generally used for medium and low pressure ball valves. 

The ball of sanitary ball valve is fixed and does not move under pressure. Fixed ball valves are equipped with floating valve seat. Under the pressure of medium, the valve seat moves and the sealing ring is pressed tightly on the ball to ensure sealing. Usually, bearings are installed on the upper and lower shafts of the ball, and the operating torque is small, which is suitable for high pressure and large diameter valves.

In order to reduce the operating torque of ball valve and increase the reliability of sealing, oil sealed ball valve appears. Special lubricating oil is injected between the sealing surfaces to form an oil film, which not only enhances the sealing performance, but also reduces the operating torque, which is more suitable for high pressure and large caliber sanitary ball valves.

 

Describe the characteristics of sanitary ball valve briefly

The stainless steel sanitary ball valve is made of SUS304 and 316L, which can meet the special requirements of various media in food and biopharmaceutical fields. Its smooth, seamless and automatic empty hand process fluid channel is also very suitable for the needs of steam in-situ cleaning. In the manufacturing process, the quality of the sanitary ball valve is controlled strictly according to FDA requirements, and the computer three-dimensional design is adopted. It is manufactured according to GMP requirements.

 

As far as I am concerned, you will know the information of the sanitary ball valves better after reading this article.
