The performance characteristics of stainless steel ball valves:   1. No maintenance, adjustment and lubrication. The installation of stainless steel ball valves is easy. The operating cost is low. The long-term operation is reliable. The surface adopts plastic spray processing technology, which...

We are very familiar with the stainless steel ball valve. However, compared with some industrial field veterans, some industrial field novices are very strange to the stainless steel ball valve. The composition of a big machine is generally composed of many small screws, valves, ball valves and other...

The cast steel globe valve is force-sealed. When the valve is closed, pressure must be applied to the disc to force the sealing face not to leak. When the medium from below the valve disc into the valve, the resistance is required to overcome the operation force. It is the friction force of the stem,...

1. The brief introduction of valves   The valve is used to control fluid flow, pressure and flow direction of the device. It is the pipeline conveying system control component. The controlled fluid may be liquid, gas, gas-liquid mixture, or solid-liquid mixture. The control function of the valve...

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....
