Stop Valve · 模型 176472
A stop valve is an unassuming yet critical component in plumbing and gas systems. Its primary function is to open and close flow of water or gas in a pipeline. This ability is especially useful in residential, commercial and even in institutional buildings. Most stop valves have two openings: one lets water in, the other lets it drain out. When you twist the handle, usually clockwise, the valve shuts off the pipe and ceases the water movement. Stop-and-waste valves are an effective way to drain lines. This innovative design keeps pipes from freezing in the winter. Some utilize ¼ turn ball for quick release. The tightness of the seal and the force required to turn the valve can vary depending on the water pressure, which could be considerable. Stop valves are available in a number of varieties, with each one designed for a specific purpose and environment. Gate valves and ball valves are the most common choices for homes and factories. Gate valves stop the flow with a metal gate. They’re most effective in the field in places where water needs to make few turns. Ball valves have a round ball inside with a hole drilled through, providing tight shutoff and easy operation—ideal for fast shutoff applications. Angle stop valves, PEX, sweat, and compression angle stop valves each connect to pipes in different fashions. Push-fit angle stops are faster to install, but they have a shorter lifespan than compression angle stops. The copper and brass valves provide long-lasting durability and resistance to rust. Needle valves — common in old refrigerators — are outlawed everywhere because they leak. Below is a summary table of the main varieties, common applications and characteristics.
