A stop valve is a key component in piping systems used to regulate, shut off, or prevent backflow of water. It is widely applied in building water supply, HVAC, water heaters, toilets, and other civil facilities. As a professional stop valve manufacturer and supplier in China, Shenchi focuses on the R&D and manufacturing of high-quality valves. Our products strictly comply with national industry standards and are based on high-quality copper and stainless steel materials, providing safe and reliable pipeline control solutions to global customers.
What is a Stop Valve?
A stop valve is a valve used in piping systems to control the on/off of water flow. It is typically installed at the water inlet of sanitary fixtures such as toilets, basins, and water heaters. By rotating the handle to open or close the internal cartridge, it enables water shut-off and regulation, allowing for equipment maintenance or replacement without the need to turn off the main water supply.
