a gate valve is a positive shut off valve for liquids and gases and should only be used in the fully open or closed positions, different temperatures and pressures must be considered to insure the correct type of valve to install. a sluice valve is a non-positive shut off valve used for heavier materials such as stone,grain,sand,etc.
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, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired.
And a globe valve is a type of valve used for regulatin fluid_dynamics in a piping, consisting of a movable disk-type element and a stationary ring seat in a generally body.
In short, location and design, but their purpose is very similar.
Unless I am very much mistaken, a shut off valve is usually placed nearest the source of the fluid or gas that the pipe will flow. For example, a natural gas shut off valve is placed outside the building at the spot where the gas enters the house. This way, utility workers, firefighters, or anyone who needs to can shut the valve and prevent gas from flowing into the house. These are designed to require a simple handle to be turned.
A gate valve is typically placed within the system (i.e. near the kitchen of a restaurant or leading to a seldom used section of a factory). These allow only part of the system to be shut down, so gas does not get wasted by flowing to places it does not need to go (in such a way that the remainder of the factory can stay operable), or to section off a leak (again, without affecting the rest of the system).
A knife gate is normally used on a sewerage system to cut though waste under the gate seat to allow for positive shut off
In globe valve we just handle small amount and small pressure of fluid while in gate valve we can handle a large amount and large pressure of fluid.

What is the functional difference between cock and valve?
The term cock and valve are used interchangeably in the English language. The term cock has in large been replaced with valve with no functional difference between the two.
What is the definition of sluice valve?
It can be defined as followed. Valve in sliding water gate.
What is the difference between check valve and nonreturn valve?
There is no difference between check valve and NRV, both are same
What is the difference between solenoid valve and control valve?
I believe that servo is motorized and solenoid is magnetically activated.
What is the functional difference between a ball valve and a butterfly valve?
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.
What is the difference between an slide gate and a sluice gate valve?
The difference is that a sluice gate is made out of cast iron while a slide gate isn't.
What is the functional difference between cock and valve?
The term cock and valve are used interchangeably in the English language. The term cock has in large been replaced with valve with no functional difference between the two.
What is the function of sluice valve in hydrant system?
regulator consisting of a valve or gate that controls the rate of water flow through a sluice
What is the definition of sluice valve?
It can be defined as followed. Valve in sliding water gate.
Is sluice valve and gate valve same?
Absolutely NOTAs well as I know, a sluice valve, also known as a gate valve, is a way to control the flow of water through a straight line pipe. They are simple in operation and quite common. Sluice valves are so named because they operate similarly to a sluice gate. By turning a handle, a gate is lowered into the pipe, blocking the flow.While is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. Sometimes, it also know as sluice valve. So you can say are same but not absolutely.
What is the difference between check valve and nonreturn valve?
There is no difference between check valve and NRV, both are same
What is a sluice used for?
A sluice valve is a gate valve. The terminology 'sluice valve' is usually applied when the gate valve is used in an open channel, like in a dam gate. It can be thought of as a flat plate that can be lowered into or lifted out of the flow channel. Of course, the actual designs are more sophisticated than that.
What is the difference between solenoid valve and control valve?
I believe that servo is motorized and solenoid is magnetically activated.
What is the functional difference between a ball valve and a butterfly valve?
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.
How can you tell the difference between intake valve and exhuast valve?
no you cant
What is the difference between a sillcock valve a boiler valve and a hose bibb valve?
They are just about the same
Difference between UV valve and XV valve?
