In industrial production, the selection of valves plays a crucial role in determining the efficiency, safety, and ease of maintenance of production lines. In many high-risk and high-demand environments, pneumatic valves have become the preferred choice for critical valve applications due to their numerous advantages. Below are some key reasons why pneumatic valves are often […]

Introduction Specialized liquid chlorine valves differ significantly from other types of valves in several aspects, mainly in material selection, sealing performance, corrosion resistance, design features, and applicable scenarios. 1. Material Selection Liquid Chlorine Valves: Typically made from corrosion-resistant materials such as LCB low-temperature steel and PFA (fluoropolymer), these materials can withstand the highly corrosive and

Emergency shutoff valves (ESDVs) are critical safety devices in various industrial processes, especially in chemical storage areas. These valves play a vital role in preventing hazardous situations such as fire, leakage, and overfilling of storage tanks by quickly isolating dangerous materials. However, the application and requirements of these valves can vary significantly depending on industry

A pressure gauge root valve is a specialized valve used to connect pressure instruments to pipelines or equipment. It is typically installed between the pressure gauge and the process pipeline or equipment to perform multiple critical functions. Primary Functions Facilitating Maintenance and Replacement: By closing the root valve, pressure gauges can be serviced, calibrated, or

Solenoid valves are essential components in many industrial systems, including chemical plants. These valves are controlled by electric current, which powers a coil (known as a solenoid) to generate a magnetic field. This magnetic field moves a plunger that opens or closes the valve, controlling the flow of liquids or gases. In chemical plants, solenoid

Liquid chlorine valves are specifically designed for handling liquid chlorine media. These valves exhibit distinctive characteristics that set them apart from general-purpose valves. Below, we delve into the key features of liquid chlorine valves: 1. Material Selection Liquid chlorine valves are crafted from highly corrosion-resistant materials such as LCB low-temperature steel and PFA (perfluoroalkoxy polymer).

Valve manifolds are essential industrial components used to integrate multiple valves for controlling, regulating, and distributing media. They play a crucial role in piping systems and industrial equipment. This article provides a comprehensive guide to help beginners understand valve manifolds, focusing on the widely used two-, three-, and five-valve types. What is a Valve Manifold?

The placement of a shut-off valve in a tank system is a critical design consideration, especially when flexible connections are involved. The general consensus among engineers is that the shut-off valve should be placed before the flexible connection. This article explores the reasoning behind this recommendation in detail and highlights the implications for safety, functionality,

I. Requirements for the Regulating Valve Air Source The air source should be clean and dry, without noticeable oil vapor, oil, or other fluids. The air source should be free of noticeable corrosive gases, vapors, and oils. The solid particles in the air source should be less than 0.1g/m³, with particle diameters less than 20µm,

The difference between the upstream and downstream pressures is called the pressure drop (△P) or differential pressure when the fluid flows through the valve. If the pipeline size is the same both upstream and downstream of the valve and the velocity is constant, the valve must reduce the fluid pressure through friction losses to produce
