What is valve corrosion? Corrosion of valves is usually understood as the damage to the metal materials of the valve caused by the chemical or electrochemical environment. Since the corrosion appears in the spontaneous interaction between the metal and the surrounding environment, the focus of corrosion prevention is how to isolate the metal from the surrounding environment or more use of non...

There are four common types of plug valves, each of which has specific characteristics and advantages. Lubricated plug valve The lubrication plug valve uses lubricant to reduce frictions and make each port tightly sealed. Lubricants are basicly base oils that increase the viscosity of moving parts, such as amorphous or fumed silica, which are injected between the valve plug surface and the valve b...

As winter approaches, the temperature gradually drops and the valves outsides are getting greater chance tobe froze. At this time, the pipeline will easily fail if not take some acts. And when it comes to some high-risk working conditions, accidents may also occur. Therefore, the anti-freezing treatment of valves is crucial to industrial equipment. Before th...

The V-type ball valve is a single-seat ball valve with a metal seat. The adjustment performance is the best in the ball valves, whose flow characteristics are equal percentages, and the adjustable ratio is up to 100:1. It has a shearing action between the V-shaped slit and the metal seat, and is especially suitable for media containing fibers, tiny solid particles, and slurry. During the...

What is the difference between a forged steel ball valve and a cast steel ball valve? The difference mainly lies in the processing technology and processing method of steel: A cast steel ball valves is a kind of ball valve that is formed by pouring liquids into a mold and then allowing them to solidify. Alloy steel is the most common casting material. Cast steel is divided into cast carbon st...

The V-type ball valve combines the optimal control characteristics of the ball valve and the butterfly valve. Its development is closely related to the advancement of technology. Today, the product is widely used because it has the following advantages. (1) The integral valve body, without any pipe flange joints, avoids the influence of pipe or bolt stress on the sealing performance of the va...
