Valves are control components in fluid transportation systems, with functions such as shutting off, regulating, diverting flow, preventing backflow, stabilizing pressure, branching, or relieving overflow. In general, most valves close clockwise and open counterclockwise, or you could say left to open, right to close. Let’s first go over some basic valve operation knowledge: since most […]
The flow rate and velocity of a valve mainly depend on the valve diameter, are also related to the resistance of the valve’s structure to the medium, and are intrinsically related to factors such as valve pressure, temperature, and medium concentration. What exactly is the relationship between the two? The flow channel area of a […]
What are the differences between valve materials? What exactly are “steel” and “iron,” what are their properties, and what is the relationship between them? Where do the terms 304, 304L, 316, and 316L come from, and what are the differences between them? Steel: A material with iron as its main element, generally containing less than […]
Valve Operating Temperature The operating temperature of a valve is determined by the material it is made of. The operating temperatures of commonly used valve materials are as follows: Valves Operating Temperature Gray cast iron valves -15~250°C Malleable cast iron valves -15~250°C Ductile cast iron valves -30~350°C High nickel cast iron valves Maximum operating temperature […]
In heavy industries such as coal chemical, polysilicon, and petrochemical production, valves, as core pipeline control equipment, directly determine the operating efficiency of the production line. Traditional wear-resistant ball valves and imported track ball valves have long faced problems such as media erosion, valve cavity jamming, valve body seizure, and short service life. Frequent replacements […]
The side-mounted ultra-low temperature online maintainable ball valve is designed by Teji Valve Group by combining the advantages of three-piece ball valves and top-mounted ball valves. Its structure is novel and unique, easy to install, and allows for online maintenance. The valve’s design and production are not limited by structure and can be designed according to user […]
