3. The leakage of sealing surfaces Causes: 1. The grinding of the sealing surface is uneven, and the sealing line cannot be formed. 2. The connection part between the valve stem and the closing part is suspended, incorrect or worn. 3. Valve stem bending or improper assembly make the closing part skew...

There are many kinds of valves, and valves are indispensable in today's life. In the process of daily use of valves, we can often see leakage faults of valves. Then, what are common causes and maintenance for the leakage of valves? We will give you a detailed introduction as follows: I. Leakage...

First, what is a ball valve?    The ball valve is one kind of valve whose opening and closing parts (the ball) are driven by the valve stem, and it rotates around the axis of the valve stem. It is mainly used for cutting off or connecting the medium in the pipeline. It can also be used...

Here are descriptions about product characteristics of electric stainless steel hard seal flanged butterfly valves. Three-dimensional eccentric structures were adopted for the electric stainless steel hard seal flanged butterfly valve. The butterfly plate is a soft and hard laminated metal sheet,...

The ball valve in the pipeline is mainly used to cut off, distribute and change the direction of the flow of the medium. It only needs to rotate 90 degrees of operation and a small rotational torque can be closed tightly. The ball valve is suitable for use of switch, cut-off valves and V-type ball valves....

The Fluorine lined ball valve is designed for the opening and closing control of pipelines with strong corrosive medium. It is widely used in petroleum, chemicals, dyeing, acid and alkali industries. It is one of the ideal choices for anti-corrosion valve equipment.   The fluorine lined ball valve...

What are electric gate valves?   When it comes to the electric gate valve, in fact, this kind of equipment needs to be used in many industries or fields. As a matter of fact, we will find that the electric gate valve in our industrial production industry is still widely used. It is very popular....

Performance differences The globe valve can be used for cut-off and flow regulation. The fluid resistance of the globe valve is relatively large, and it is more laborious to open and close. Because the distance between the valve plate and the sealing surface is short, the opening and closing stroke...

Many kinds of valves like globe valves, gate valves, butterfly valves, check valves and ball valves are indispensable control components in various pipeline systems. Each valve is different in appearance, structures and even functions.   However, there are some similarities between the globe valve...

Third, we should implement a diversified sales strategy, strive to open up the international market and expand exports. According to the statistics of China Forged Steel Valve Association, at present, China's forged steel gate valve industry has a serious overcapacity, accounting for about 40% of...
