How much does a plumber charge to change a gate valve?

Can you replace the inside of a gate valve?

Do gate valves go bad?
Gate valves tend to wear out over time. And corrosion can cause the disc to stick in either the open or closed position. When the handle is forced, the stem leading from the handle to the disc will often break, rendering the valve useless.
What is the difference between a gate valve and a stop valve?
Stop valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. If the valve is put in backward, the flow will force the gasket away from the top of the valve. Gate valves are called ‘full-flow’ valves; there’s a direct unobstructed path for flow right through the middle of the valve.
Which way do you turn a gate valve to close it?
Gate valves close by turning the wheel clockwise until the water is off. Ball valves close by turning the straight handle a quarter turn clockwise until the water is off. To verify the water is off, turn on the hose bib next to the house valve. As you turn the house valve off, the water from the hose bib should stop.
Is a gate valve better than a ball valve?
Ball valves are more effective at forming a tight seal and have more reliability and longevity than gate valves, but tend to be more expensive. They are often used for shutoff and control applications. Because ball valves can open and close immediately, they are more likely than gate valves to cause water hammer.
