How to save the valve cost?
Design and development: Cost is designed (accounting for 70% of the valve cost) The first step in cost control is on the drawing board, not on the production line. Implement value engineering (VE) and value analysis (VA): Core idea: Analyze the functions of the product (basic functions, auxiliary functions, unnecessary functions), and seek ways to […]
Valve selection for corrosive media such as strong acids and strong alkalis
valve selection for corrosive media valve selection for corrosive media such as strong acid and alkali is a very important and professional problem. Improper selection will lead to rapid failure of valves, leakage of media, safety accidents, environmental pollution and production interruption.The following are the key points, steps and common valve types for the selection […]
Can globe valve vs gate valve be used at will?
Globe valve vs gate valve: similar functions, but cannot be used at will. Globe valve vs gate valve are two of the most common and similar valves. Many users, especially beginners, often have a question: they both seem to be used for “opening and closing”, so can they be used interchangeably? The answer is: although […]
How to choose reliable industrial valves suppliers in Chinia?
1. Quality considerations In supply chain management, quality is the cornerstone. The practical value of products depends on their quality, which sets the standards for end-consumer goods. This factor impacts market competitiveness, a company’s share, and reputation. Therefore, quality should be the top priority when selecting suppliers. 2. Cost considerations Price plays a pivotal role […]
What different between gate valves and butterfly valves?
Gate valves and butterfly valves are both widely used, but they differ in structure, operation, and working conditions. This article explains these differences to help you choose the right valve for your needs. Gate valves work by using a vertical gate to block or allow flow in a pipeline. They are commonly used in both […]
How to install the industrial valves?
These regulations apply to the installation of gate valves, globe valves, ball valves, butterfly valves, and pressure reducing valves in petrochemical plants. The installation of check valves, safety valves, gate valves, and steam traps is governed by relevant regulations. These regulations do not apply to the installation of valves on underground water supply and drainage […]
How to find the causes and solutions for industrial valve leakage
Valve leakage is a common issue in industrial production and pipeline systems. It can cause resource waste, pollution, and even safety incidents. Below are the typical causes and solutions for valve leakage, divided into internal leakage (when the valve does not close tightly) and external leakage (when the valve body or its connections leak). I. […]
Why is 304 not recommended for bolts of industrial valves?
What are the basic differences between 304,304L,316 and 316L materials? Â 304,304L,316 and 316L are the stainless steel materials commonly used in flange joints (including flanges, sealing elements and fasteners). Â 304,304L,316, and 316L are stainless steel grades certified by the American National Standards Institute (ANSI) or American Society for Testing and Materials (ASTM), classified […]
What different between trunnion ball valves and floating ball valves
Floating Ball Valve A floating ball valve works because the ball can move slightly when pressure is applied, pressing against the outlet seat to create a seal. The main parts are the valve body, floating ball, seat seal, and stem. How it works: Turning the valve stem 90 degrees moves the ball to open or […]
How to choose the right types of strainers
Principles and requirements for strainers selection A strainers is a compact device that removes small solid particles from liquids, ensuring the proper operation of equipment. When fluid enters the filter cartridge equipped with a specified mesh strainers, impurities are retained while clean filtrate is discharged through the outlet. For cleaning maintenance, simply remove the detachable […]
How to grinding the disc of gate valves
The grinding the disc of gate valves process comprises three stages: rough grinding, finish grinding, and polishing. Rough grinding eliminates defects such as scratches, indentations, and pits on sealing surfaces, achieving high flatness and precise surface roughness to prepare for finish grinding. This stage employs coarse-grit abrasives (paper or cloth) with 80-280 grit particles. While […]
What different between full port ball valves and V port ball valves
Full port ball valve and V-type ball valve are two types of ball valves with different structures and different functional priorities. They are significantly different in design, flow characteristics, regulation performance and application scenarios. This article explains what different between full port ball valves and V port ball valves. Additionally, it focuses on what different […]
