A ball cock is self closing a gate is manually turned on and off
Gate valve shuts straight down to close off the line. A ball valve has a hole through it and is rotated to close the line. Gate is used for liquid and ball is for gas but can also be used for liquid.
A gate valve is a valve that opens by lifting a gate from the path of the fluid. A ball valve is a valve that opens by turning a handle attached to a ball inside the valve. The ball has a hole in the middle so that when the hole is lined up the input side and the output side of the valve, flow occurs. A globe valve is a type of valve used for regulating flow in a pipe, consisting of a movable disk-type element and a stationary ring seat in a spherical body. Usually the globe is moved in and out of the flow by a handle connected to a threaded stem.
A valve normally with a stainless steel ball inside it in lieu of a gate or washer such as a globe pattern valve
gate valve. globes are used for throttling and have far too many turns. ball valves are not made for thick stuff. this question was on the inter-provincal exam they had globe valve, gate valve, diaphragm valve and piston valve. for answers too choose from.
ALWAYS USE BALL VALVE. Gate valve will leak. meaning it will let some water come through valve after time if not a lot. They just don't hold up after time.

An air valve is a spring loaded plastic valve for ventilation. A gate valve is an old fashioned type of water valve where turning a handle lowers a blocking gate over the water inlet. Any sensible plumber now uses ball valves instead.
a gate valve is a valve you turn the handle round and round until it shuts off a ball valve is a valve with a lever that you turn 1/4 turn and its off hope this helps plumber paul

For Ball valve only,as it gives more full bore flow,unlike wedge block,slow operating in Gate valve.

A plug valave uses a cilindrical kind of element to shut down the flow. The ball valve uses a spherical element to sut down the flow
A ball valve is a ball with a hole through it that rotates around its axis to expose the hole for flow or the solid wall of the ball for no flow. The butterfly valve is a flat piece that is supported in the middle by a shaft that opens or closes when the shaft is rotated.
Application is shutting off supply, usually water. -Gate valves are 'Old hat' and inefficient, get a new ball valve instead.
Ball valve is usually preferable. full flow with no restriction and a lot easier and faster to turn off when needed.
