When a pipe leaks, a plumber’s first line of defense is a control valve. Here are four valves that every plumber will always find in the field. Gate Valve A gateway valve is a staple in the plumbing industry because it has a practical design that effectively controls water flow. A plumber can increase or decrease the water flow in a pipe with this valve by twisting it. Ball Valve Ball valves are the most reliable parts for plumbers. Unlike a gate valve, a ball valve has a round mechanism with a gap in it. It’s attached to a lever on the outer handle. The handle has a parallel and a perpendicular setting. The parallel position lets water flow through a pipe, and the perpendicular position closes the valve. Globe Valve A globe valve regulates water flow. It’s called a globe valve because it has a circular knob. There is a stopper inside of this valve. The knob on the top of the valve lowers and raises the stopper. Globe valves can handle a lot of water pressure, so they’re often attached to outdoor faucets. Check Valve Check valves move water in one direction. They can also prevent water flow in a pipe in the opposite direction. Most certified check valve suppliers sell devices with no control handles.
