Difference between industrial valves and household valves?

There are significant differences between industrial valves and household valves. Industrial valves are mainly used in various industrial sectors such as petrochemicals, water treatment, electricity, and mining. On the other hand, household valves are used in the pipeline systems of homes or commercial buildings, such as bathrooms, kitchens, and public restrooms.

Industrial valves are typically made from cast iron, steel, and stainless steel and have intense heat and corrosion resistance. In contrast, household valves are usually made from copper and brass alloys such as cast copper and forged copper and are generally smaller in size and less complex in design.

Industrial valves must meet performance and specification requirements to withstand harsh usage environments and meet relevant standards and regulations. In contrast, household valves must be stable and safe to use, operate easily, and meet national standards and regulations.

Standard household valves include globe, ball, axial flow control, and cast iron gate valves. The specifications, pressure, temperature, and other characteristics of household valves vary depending on the type and application. For example, globe and axial flow control valves are mainly used in hot and cold water systems, while ball valves are commonly used in gas or liquid pipelines.

Analyze the characteristics of standard household valves, such as styles, materials, specifications, pressure, and temperature.

Standard household valves are plug, ball, axial flow control, and cast iron gate valves. The materials and specifications of these valves can vary widely depending on the type and application. For example, plug valves are typically made from copper or stainless steel, with specifications ranging from 1/4 inch to 4 inches, pressure below 125 PSI (about 8.6 bar), and temperature ranging from -10℃ to 120℃.

Ball valves, which are often used in bathrooms, kitchens, and HVAC systems, have materials ranging from copper to stainless steel, with specifications ranging from 1/4 inch to 2 inches and a pressure range of 100 PSI (about 6.9 bar) or less and temperature going from -20℃ to 200℃.

Plumberstar flow control valves are also often used in showers and water faucets, with materials ranging from copper to stainless steel, specifications of up to 3/4 inch, pressures under 100 PSI, and temperature ranges from -20℃ to 200℃.

Cast iron gate valves are standard and economical, generally used in home water supply pipes. They are made of ductile iron, with specifications ranging from 1/2 inch to 2 inches, pressure below 200 PSI (about 13.8 bar), and temperature ranging from -20℃ to 200℃.

Household valves are smaller, simpler in design, and have lower performance requirements than industrial valves. Therefore, the price of household valves is relatively low. Choosing products from reputable brands and manufacturers with complete certification is recommended when purchasing household valves.
