This article is about the differences between forged steel valves and cast steel valves. Which one is good?    The cast steel valve is one kind of cast alloy. Cast steel can be divided into cast carbon steel, cast low alloy steel and cast special steel. Cast steel is a kind of steel casting...

Many valves are now essential control components in all kinds of piping systems, such as globe valves, gate valves, butterfly valves, check valves and ball valves. Each valve is different in appearance, construction and even function and usage. However, globe valves and gate valves have some similarities...

Ball valves are divided into pneumatic ball valves, electric ball valves and manual ball valves. The ball valve body can be one whole part, and it can also be combined. The ball valve is evolved from the plug valve. Its opening and closing parts are as a ball and it uses the ball around the stem axis...

1. From the structure The one-piece ball valve is integrated by the inside of the ball, PTFE ring and lock nut. The caliber of the ball is slightly smaller than that of the pipe diameter. It is similar to the wide ball valve. The two-piece ball valve is composed of two parts. The sealing effect is better...

The opening and closing parts of the gate valve are the gate plate. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and closed, and it is not adjusted and throttled. The gate plate has two sealing faces. The most commonly...

What Is the Forged Steel Gate Valve? The forged steel gate valve is suitable for a small caliber pipeline with Class150-2500. The suitable working temperature is -29-425℃ (carbon steel) or -29-500℃ (stainless steel). The forged steel gate valve is used to cut off or connect the medium in the pipeline....

The performance of stainless steel pneumatic ball valves was optimized comprehensively, which can improve the quality and efficiency of related production industries. Excellent equipment is the key to supporting production. If the equipment is backward, the goal of development will be difficult to achieve....

The double ball valve is made by natural rubber synthesis. It has many characteristics like high elasticity, tear resistance, high wear resistance and corrosion resistance. Therefore, it can be used not only for tailings filling, but also for slurry delivery, especially for those with good quality and...

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...
