What is the difference between a control valve and a gate valve in a stand pipe system?
a gate valve is a one way totally open or closed valve, a control valve is a variable valve.
What is the difference between gate valve and OS and Y valve?
OS and Y stands for Opposed Stem and Yoke.
What are the basic components of a gate valve?
the gate and the valve.
What is the difference between gate valve and globe valve?
The external housing (shell) of gate and globe valves are similar, but the globe valve is designed to serve as a regulating valve, meaning that it can adjust the flow by the percentage of the opening. However, the gate valve is not designed to regulate flow, but to stop the flow. A gate valve should always be either fully open or fully closed. The main difference is in the form of the inner elements and the form of the flow inside the valves. In addition, the gate valve may have a rising or non rising stem while the globe valve is typically a rising stem design. The direction of flow through a gate valve is not important. However a globe valve has a flow direction indicated on the outer shell (body) which indicates the direction of flow from beneath the seat. In a gate valve, the closure element is a plate or disk which travels parallel to the plane of the seat. The gate in a dam is a well known example. In a globe valve, the closure element is usually called a "poppet", and it travels perpendicular to the plane of the seat. There are specific advantages and disadvantages to each type depending on the application. The application for a globe valve is regulating flow. It is not well suited for full stop isolation. The gate valve is an isolation valve and not designed to regulate flow.
What is the functional difference between gate valve and sluice valve?
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.
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.

OS and Y stands for Opposed Stem and Yoke.
Difference between globe valve and gate valve?
The Gate valve is the stop valve & the Globe valve is the fluid Regulating valve.
What is the difference between an air valve and gate valve?
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.
What is the difference of gate valve to gate valve?
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
In what applications is a gate valve used?
A gate valve, or a sluice vault, is used when you want as little friction as possible when opening and/or closing a flow in a pipe. In the petroleum industry a knife valve is used to basically cut through the liquid.
What is a knife gate valve?
It is a type of shutoff valve with a thin valve disc which is opened or closed by sliding the disc in/out with a sliding handle, perpendicular to the fluid (or powder/grain) flow.
What is the difference between reflux valve and check valve?
A check valve allows for flow in one direction and a gate valve is used for positive shut off and a globe valve is used for throttling
