What are Industrial Valves and Domestic Valves?
Industrial Valves
Industrial valves are mechanical devices designed to control the flow of liquids, gases, or solids in large-scale industrial systems. They are widely used in industries such as oil and gas, chemicals, power generation, wastewater treatment, and food processing. Industrial valves must meet stringent requirements for durability, high-pressure resistance, extreme temperatures, and corrosive environments.
Examples:
-
In an oil refinery, industrial gate valves are used to fully open or close the flow of crude oil under pressures of hundreds of bars.
-
In a brewery, stainless steel ball valves control the flow of liquid ingredients in a highly sanitary environment.
Domestic Valves
Domestic valves are used in household, office, or small-scale piping systems. They are simpler in design, easier to install, and more cost-effective than industrial valves. Domestic valves primarily serve basic needs like water supply, drainage, or air conditioning.
Examples:
-
A shut-off valve in a kitchen controls the water flow to a sink.
-
A check valve in a solar water heater prevents hot water from flowing back into the cold-water line.
Comparison of Industrial Valves and Domestic Valves
To better understand the distinctions, let’s compare these two types of valves based on specific criteria:
1. Design and Construction
-
Industrial Valves:
-
Complex construction, often made from high-strength materials like stainless steel, ductile iron, or specialized alloys.
-
Available in various sizes, from a few millimeters to several meters, to suit large pipelines.
-
Can incorporate automation technologies, such as electric or pneumatic actuators.
-
Example: A 1-meter-diameter industrial butterfly valve used in a municipal wastewater treatment system.
-
-
Domestic Valves:
-
Simple, compact design, easy to use.
-
Typically made from brass, PVC, or galvanized steel.
-
Primarily manually operated, requiring no complex technology.
-
Example: A brass angle valve installed under a kitchen sink.
-
2. Applications
-
Industrial Valves:
-
Used in systems requiring high precision and safety, such as chemical plants, power plants, or offshore oil rigs.
-
Can operate in harsh conditions, including temperatures up to 500°C or pressures of hundreds of bars.
-
Example: An industrial globe valve regulates steam flow in a steel manufacturing plant’s furnace.
-
-
Domestic Valves:
-
Serve everyday needs like water supply, drainage, or small-scale irrigation systems.
-
Operate under normal conditions with low pressure and temperature.
-
Example: A PVC shut-off valve used in an automated garden irrigation system.
-
3. Durability and Lifespan
-
Industrial Valves:
-
Designed for continuous operation, with a lifespan of 10-20 years if properly maintained.
-
Resistant to corrosion, vibration, or heavy impacts.
-
Example: Safety valves in nuclear power plants are built to function reliably under radiation and high-pressure conditions.
-
-
Domestic Valves:
-
Lower durability, with an average lifespan of 5-10 years, depending on material and usage.
-
Prone to damage in adverse conditions, such as water with high mineral content or sediment buildup.
-
Example: A plastic valve in a toilet tank may leak after a few years if not regularly cleaned.
-
4. Cost
-
Industrial Valves:
-
Higher cost due to premium materials, complex design, and compliance with international standards like API, ASME, or ISO.
-
Example: A 200mm stainless steel industrial ball valve can cost from a few million to tens of millions of VND.
-
-
Domestic Valves:
-
Affordable, suitable for the average consumer’s budget.
-
Example: A PVC water shut-off valve costs as little as a few tens of thousands of VND.
-
5. Technical Standards
-
Industrial Valves:
-
Must comply with strict standards like API 600 (gate valves), ASME B16.34 (pressure valves), or ISO 5208 (leak testing).
-
Often accompanied by quality certifications from reputable organizations.
-
Example: Industrial valves used in the oil and gas industry must be tested and certified by organizations like DNV or ABS.
-
-
Domestic Valves:
-
Require less stringent standards, typically meeting basic national regulations.
-
Example: Domestic valves for household water supply only need to comply with Vietnam Standards (TCVN).

ASTM A105 is the standard specification for forged carbon steel components developed by the American Society for Testing and Materials (ASTM). This material is designed exclusively for the manufacture of piping system components such as flanges, valves, and high-pressure fittings.
In industrial piping systems, flanges play a critical role by securely connecting pipes, valves, pumps, and other equipment. They ensure tight sealing, mechanical stability, and easy disassembly for maintenance.
To guarantee proper identification and compliance with international standards, every flange is marked with detailed information, including standard, pressure rating, material, and manufacturing data. These markings are not just identification codes – they are essential for quality control, traceability, and system safety.
In modern hydraulic systems, where fluids are transmitted under extreme pressure, every component plays a vital role in ensuring overall performance and safety. Among these components, steel flanges are indispensable. They are used to connect pipes, valves, pumps, and other equipment, creating a secure and leak-proof joint that withstands both high pressure and temperature.
Today, Korean steel flanges have gained strong recognition in the industrial market thanks to their superior quality, durability, and compliance with strict international standards. Their exceptional ability to endure high pressure makes them an ideal solution for hydraulic systems and other demanding industrial applications.
In industries operating in marine and coastal environments, the durability and resistance of materials to corrosion are critical factors in ensuring safety and long-term performance. Among the most essential components in pipeline systems for marine applications are steel flanges, which connect pipes, valves, and fittings. For environments exposed to seawater, Korean steel flanges have proven to be an optimal solution due to their superior quality, corrosion resistance, and compliance with international standards.
In modern industries, pipeline systems are required to operate under increasingly complex and demanding conditions. From oil and gas, petrochemicals, power plants, to marine engineering, the performance and safety of pipeline connections play a critical role in ensuring stability and minimizing risks. Among the essential components of these systems, Korean steel flanges stand out for their superior leak-proof properties in high-pressure environments, helping businesses optimize operations while ensuring compliance with safety standards.
In industrial systems, especially in the oil and gas, energy, chemical, and construction sectors, steel flanges play a vital role in connecting pipelines, equipment, and valves. To ensure safety and operational efficiency, flange products must strictly comply with national and international quality standards. Among these, the KS (Korean Standards) system stands out as a benchmark widely applied to Korean steel flanges, ensuring stability, safety, and long-term durability.
