Are valves made by JKLONG good for water supply system?Yes. Brass valves are commonly used for water supply lines because brass offers good corrosion resistance, mechanical strength and long service life in many plumbing applications. For water systems, buyers usually choose brass ball valves for quick shut-off, brass gate valves for isolation and brass check valves for backflow prevention.
What are JKLONG valves used for?JKLONG valves (JKL Valves) made by brass, ductile iron and stainless steel. They are used to control, shut off, regulate or prevent reverse flow in water, gas, and plumbing. Common valve types include ball valves, gate valves, check valves, globe valves and press-fit valves. They are widely selected for their durability, corrosion resistance and reliable sealing performance.
How to choose between brass valves, ductile iron valves, and stainless steel valves?Brass valves are suitable for small to medium-sized low-pressure water pipelines in civil buildings, featuring stable performance, resistance to rust, and long service life. Ductile iron valves are suitable for medium to large-sized civil water supply pipelines, characterized by low cost and stable operation. Stainless steel valves are mostly used in industrial applications, possessing strong corrosion resistance, acid and alkali resistance, and a significant cost advantage over brass for large sizes.
How do I choose the right JKLONG valve?To choose the right valve, confirm the application media, pipe size, connection type, pressure requirement, operating temperature and installation space. For quick shut-off, choose a ball valve. For pipeline isolation, choose a gate valve. For preventing reverse flow, choose a check valve.
Can JKLONG brass valves be used for gas systems?Selected brass valves can be used in gas systems when they are designed and tested for gas applications. Buyers should confirm sealing performance, thread standard, pressure rating and local gas safety requirements before ordering. For gas projects, it is best to work with a brass valve manufacturer that can provide suitable specifications and quality control.
Why choose JKLONG metal valves instead of plastic valves?Brass valves and valves made by ductile iron and SS are stronger, more durable and more heat-resistant than many plastic valves. They are often preferred for water, gas, heating and plumbing systems where long-term sealing, thread strength and mechanical reliability are important. Plastic valves may be suitable for some low-pressure or lightweight applications, but metal valves is usually a better choice for demanding installations.
