Valve Parameters
Nominal Diameter The nominal diameter (DN) is a numerical designation used to define the size of all piping system components, distinguishing it from those parts that are designated by thread or outside diameter. Another method for specifying valve sizes is the American system, which uses inches as the unit of measurement. For example, a DN50 […]
Application of Concentric type Resilient Seated Butterfly Valve in Marine Vessel
Concentric type resilient seated butterfly valves are commonly used in marine vessels for several reasons: Leakage Prevention: The resilient seat provides a tight seal, reducing the risk of leakage in critical applications. This is crucial in marine environments where leaks can lead to significant safety and operational issues. Corrosion Resistance: These valves are often made from […]
Classification of valve
There are many types of valves, and they can be classified in various ways. Classification by automation and actuation Automatic Valves: These valves operate automatically relying on the medium (liquid, gas, steam, etc.) itself. Examples include safety valves, check valves, pressure reducing valves, and automatic exhaust valves. Actuated Valves: These valves are operated manually, electrically, […]
Application of Single Door Check Valve
A single door check valve, also known as a swing check valve, is used in various applications to allow fluid (liquid or gas) to flow in one direction only and prevent backflow. Here are some common applications: Water Supply Systems: To prevent backflow in municipal water supply systems. In residential plumbing to stop contaminated water […]
Standards for Use of Marine Valves
Specifies dimensions for metal valves used in marine applications. Classification Societies Classification societies provide additional guidelines and standards specific to marine applications. Some of the major classification societies include: American Bureau of Shipping (ABS): ABS Rules for Building and Classing Marine Vessels: Includes requirements for the design, construction, and testing of valves used in marine […]
Design standards and materials for single door check valves
Design Standards for Single Door Check Valves Single door check valves are designed and manufactured according to various international standards to ensure quality, reliability, and compatibility. Some of the common standards include: API 594: Covers the requirements for check valves, including design, manufacturing, testing, and inspection. ASME B16.34: Provides standards for pressure-temperature ratings, dimensions, and materials for […]

Concentric type butterfly valves play vital roles across various sectors within the petroleum (oil and gas) industry due to their reliability, versatility, and cost-effectiveness. Here are the main applications of concentric type butterfly valves in the petroleum industry: Flow Control in Pipeline Systems: Crude Oil Pipelines: Regulating the flow of crude oil within pipelines during transportation […]
The Application of Concentric type Butterfly Valve in Offshore Drilling Platforms
Concentric type butterfly valves find several applications in offshore drilling platforms due to their reliability, compact design, and ease of operation. Here’s how centerline butterfly valves are used in offshore drilling platforms: Flow Control in Seawater Systems: Concentric butterfly valves are used to control the flow of seawater for different purposes: Cooling Systems: Regulating seawater flow […]
Marine valves in the shipbuilding industry（tanghai Valve)
Marine valves play a crucial role in shipbuilding, managing the flow of various fluids such as water, fuel, oil, and gases throughout a vessel. These valves are essential for the operational efficiency, safety, and maintenance of a ship. Here are some common types of marine valves used in shipbuilding and their functions: Gate Valves Function: […]
Dual plate check valve in marine valve
A double plate check valve, also known as a dual plate check valve or wafer check valve, is a type of non-return valve commonly used in various fluid systems on ships. It is designed to allow fluid to flow in one direction while preventing backflow, ensuring that the fluid flow is unidirectional. Here are some […]
