[0002] Angle valve, also known as triangular valve, angle valve, angle water valve, or angle stop valve, is a plumbing hardware accessory used to control the opening and closing of media (hot and cold water, heating) on the installation pipeline. Angle valves are mostly used for water and electricity installation in the decoration industry and are important plumbing accessories. It has the characteristics of small flow resistance and larger flow coefficient than single-seat valves. Angle valves are similar to ball valves. Their structure and characteristics are modified from ball valves. The difference from ball valves is that the outlet and inlet of the angle valve are at a right angle of 90 degrees.
