I. Classification and Characteristics of Ball ValvesClassification by Structural FormFloating Ball ValveThe ball of a floating ball valve can generate a slight floating force under the action of the medium pressure, thus forming a good sealing effect on the sealing surface. This type of ball valve h

Outstanding Sealing PerformanceWelded floating ball valves can achieve a highly tight fit between the ball and the valve seat through precise manufacturing processes, resulting in an excellent sealing effect. This means that when transporting various media, it can minimize or even completely elimina

In today's complex industrial world, the precise control of fluids plays a vital role in the stable operation of various fields. And J-VALVES socket weld gate valves, relying on the powerful strength of Made in China, are extending the olive branch of win-win cooperation to all sectors, jointly open

In the complex and high-risk production system of the petrochemical industry, valves are like the "nerve hubs" of the industrial system, playing a crucial role in ensuring production safety and efficiency. As petrochemical processes involve extreme conditions such as high temperature, high pressure,

I. Design FeaturesThe three-way ball valve is composed of components such as the valve body, ball, valve stem, sealing ring and valve cover. There are three channels inside the valve body, and there are through holes on the ball. The fluid flow direction is controlled by driving the ball to rotate t

In industrial fields such as petrochemical and natural gas transportation, the complex working conditions of high temperature and high pressure pose stringent requirements for the performance of valves. Thanks to its unique structural design and excellent performance, the trunnion ball valve has bec

In the industrial field, the material selection of high-performance ball valves is extremely important, especially its corrosion resistance, high temperature resistance and wear resistance. The following is a material selection analysis for these three properties: I. Corrosion resistanceStainless st

In industrial piping systems, flange gate valves and welded gate valves are two common types of valves. Their selection strategies are closely related to pressure ratings. The following are selection suggestions for these two types of valves based on different pressure ratings.I. Low-pressure workin

Selection Key Points(I) Working Pressure and TemperatureSelect appropriate pressure and temperature ratings according to the working conditions. The pressure ratings of DBB ball valves usually cover 150, 300, 600, etc., with a nominal pressure range of 16-100, and an applicable temperature range fro

I. The Rise of Chinese Ball Valve Technology(I) Technological Innovation and Alignment with StandardsThe Chinese ball valve industry has undergone a transformation from imitation to independent innovation in the past few decades. Today, Chinese ball valve manufacturers can not only produce products

As one of the emerging economies in the world, India has witnessed rapid industrial development, and the demand for various industrial equipment is constantly growing. As an important fluid control device, ball valves are widely used in multiple fields in India such as petroleum, natural gas, chemic

In a low-temperature environment, the performance and reliability of gate valves face severe challenges. Low-temperature media such as liquefied natural gas (LNG), liquid oxygen, and liquid nitrogen have extremely low temperatures and pose special requirements for the materials and structure of valv

Ultra-low temperature conditions are commonly found in fields such as liquefied natural gas (LNG) storage and transportation, and cryogenic separation processes, with operating temperatures as low as -162°C or even lower. Under such extreme conditions, the material selection and anti-freezing struct

The 3PC forged steel ball valve, also known as the three piece forged steel ball valve, gets its name from its unique structural design composed of three main components. These three components are respectively two pipe joints and one main part. The two pipe joints can be conveniently installed on t

I. API 600 Gate Valve Standard(I) Standard OverviewAPI 600 is a standard for steel gate valves with flanged ends and butt-weld ends and bolted bonnets used in the oil and gas industry. This standard applies to gate valves with a nominal size (DN) > DN50 (NPS2), covering the design, manufacture, insp

I. Sealing Performance(I) Wedge Gate ValveThe sealing performance of the wedge gate valve mainly depends on the tight combination of the wedge-shaped gate and the valve seat. Its sealing surface forms a certain angle with the vertical centerline (usually 2°52', 3°30', 5°, 8°, 10°, etc.). This design

I. High Efficiency of Welded Gate Valves(I) Quick Installation and ConnectionThe welded gate valve directly integrates the valve and the pipeline through welding, eliminating components such as bolts and gaskets required for traditional flange connections. This significantly reduces installation tim

I. Advantages of Traditional Sealing Design(I) Rigid Gate and Flexible GateThe gate of a wedge gate valve can be designed as a rigid gate or a flexible gate. The rigid gate has strong integrity and is suitable for high-pressure working conditions. The flexible gate, through the elastic groove in the

I. High-strength Characteristics of High-pressure Forged Gate ValvesThe core advantage of high-pressure forged gate valves lies in their high-strength valve body structure. Compared with traditional cast valves, the forging process significantly improves the density and uniformity of the valve body,
