What are the Differences between Forged Steel Ball Valves and High Pressure Ball Valves?(Part Two)

Note the following points in the use and maintenance of high pressure ball valves.  When ball valves are closed, there still pressure fluid exits inside the valve body. Lubricate high pressure ball valves with lubricating grease. The lubrication grease should be compatible with metal materials, rubber parts, plastic parts and working media of ball valves. Lubricate grease on the surface of...

What are Differences between Forged Steel Ball Valves and High Pressure Ball Valves?(Part One)

Both forged steel ball valves and high pressure ball valves are widely applied to industries. What are the differences between these two kinds of valves? Materials of the valve body of the ball valve can be roughly divided into two kinds: casting materials and forging materials. Materials of forged steel ball valves are made by forging, and there are various forging materials including A105, LF2,...

Nine Advantages of Forged Steel Ball Valves

One of the advantages of the forged steel ball valve is its small flow resistance which can be zero actually. The sealing performance of the forged steel ball valve is reliable because most valve seats of forged steel ball valves are made of PTFE elastomer so that the effect of complete sealing can be achieved under high pressure and temperatures.  The forged steel ball valve has good corros...

Matters Needing Attention of Forged Steel Gate Valves (Part Two)

After the pressure test of forged steel gate valves, the pressure of the gas and water in the sea cavity rises as the temperature rises. In order to grease the valve smoothly, the valve cavity should be empty and the pressure of the valve need to be reduced before the valve is greased. Reducing the pressure of the gate valve in time can ensure the safety of the forged steel gate valve and the grea...

Matters Needing Attention of Forged Steel Gate Valves

The disc of the forged steel gate valve is the gate, whose direction of movement is perpendicular to the flowing direction of the fluid. The forged steel gate valve can only be fully open or fully closed, and it can not be used as control valves and throttle valves. There are two sealing surfaces of forged steel gate valves' gates, and the most common pattern is that the two sealing surfa...

Why Forged Steel Ball Valve Led to Constant Innovation?

From the global economic crisis of years ago to later ease-up, and the economic upturn now, the changes of economy have resulted in the growth and development of valve industry. But why forged steel ball valve, the common valve, led to constant innovation of traditional valve industry? Traditional manufacturers of forged steel ball valve has been in a relatively flat period through the first few ...
