Leakage of valve body: the reason: 1. The valve body has blisters or cracks; 2. Cracking during repair welding of valve body deal with: 1. Polish the suspected cracks and etch them with 4% nitric acid solution. If there are cracks, they can be reveal...
Valve selection basis 1. Fluid working conditions (pressure and temperature) 2. The nature of the fluid (corrosive, etc.) 3. The purpose of selecting the valve (throttling, pressure control, etc.) Since the valve has a wide range of uses, it also pla...
1. Correctly select the type of valve The correct choice of valve type is based on the designer's full grasp of the entire production process and operating conditions as a prerequisite. When selecting the valve type, the designer should first grasp t...
1. Ball valve selection instructions Ball valves are suitable for low temperature, high pressure, and high viscosity media. Most ball valves can be used in media with suspended solid particles, and can also be used in powder and granular media accord...
1. Working principle of PVC plastic diaphragm valve: The plastic diaphragm valve uses a corrosion-resistant lining valve body and a corrosion-resistant diaphragm instead of the valve core assembly, and the movement of the diaphragm is used for adjust...
The definition of "valve" is a device used to control the direction, pressure, and flow of fluid in a fluid system. A valve is a device that allows the medium (liquid, gas, powder) in the piping and equipment to flow or stop, and can control its flow...
Pneumatic butterfly valve is usually a combination of pneumatic actuator, valve body and some accessories connected after installation and debugging. This article mainly introduces the matters needing attention in the field use of pneumatic butterfly...
The statement ‘preference for PVC pipes’ really depends on the application. Iron pipes and PVC pipes have vastly different properties that allow them to be used in different situations. In the water industry (and household plumbing etc.) it is prefer...
