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...

As we all know that the valve body like carbon steel (WCB, WCC, LCB, LF2, A105), stainless steel (SS304, SS316, F304L, F316L), hastelloy (Alloy 20) etc., or even in the trim material always use metallic materials. Most of the corrosion of metallic materials occurs in the atmosphere, which contains corrosive components and corrosive factors such as oxygen, humidity, temperature changes and pollutan...

Valves are control components in fluid transfer systems, with a variety of different functions such as stopping, regulating, diverting, preventing backflow, stabilizing pressure or overflowing pressure relief. Therefore, it can be used in many fields and has a wide range of uses. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurr...

The valve body, bonnet and wedge (disc) are the main parts of the valve, which directly bear the medium pressure. The materials used must comply with the provisions of "pressure and temperature rating of the valve". Common materials are as follows: 1. Grey Cast Iron Grey cast iron is suitable for water, steam, air, gas and oil media with nominal pressure PN ≤ 1.0MPa and temperature between -...

The working principle of the forged steel ball valve is to make the valve unblocked or blocked by rotating the valve stem. The ball valve is easy to switch, small in size, can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and spherical surface are often in a closed state, which is not easy to be eroded by the medium, and...
