This article will provide you with a detailed guide to ball valve installation, including important steps such as pre-installation preparation, inspection of the ball valve, preparation of pipelines, installation steps, connecting pipelines, testing of ball valves, and maintenance. By following t...
Ball valve is a type of valve widely used in the field of fluid control. This article will deeply explore the working principle, structural characteristics and many advantages of ball valves to help readers better understand and apply ball valves.
Ball valves are a fluid control device widely used in a variety of industrial and commercial applications. Due to their outstanding performance, durability and ease of maintenance, ball valves have become the solution of choice for many applications. When selecting a ball valve, it is important t...
Back seat refers to a sealing design feature that prevents medium leakage to stuffing box in certain types of valves, such as globe valves and gate valves.
Gate valves and butterfly valves are both types of flow control valves used in various industries to regulate the flow of fluids through pipes or pipelines. They have distinct designs and applications, and the main differences between them include their structure, operation, and typical use cases:
The ISO 15848 standard specifies the measurement, testing, and evaluation procedures for fugitive emissions from industrial valves. This standard is divided into two parts.
From November 1, 2022, the American Petroleum Institute (API) officially starts to implement API 6D Standard, a revision from the 24th edition to the 25th edition. The notification was issued in November, 2021. API 6D 25th Standard is a significant revision of design standard of API 6D Ball Valve...
The American Petroleum Institute (API) standards for ball valves include API 6D and API 608, updated in 2021. These standards provide specifications for design, manufacturing, testing, and documentation of ball valves used in various industries, including the oil and gas sector. Here are the main...
The "Coefficient of Flow," often referred to as the "Flow Coefficient" or simply "Cv," is a measure of the efficiency of a valve in controlling fluid flow through a system. It is a dimensionless number that provides an indication of how much flow a valve can allow for a given pressure drop across...
