What does valve mean?
A valve in the Plumbing sense is a mechanical device to open or close the water flow. It can be a screw operation called a 'Gate Valve' or a simple 1/4 turn handle called a 'Ball Valve' . These are more modern and efficient.
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.
Why shouldn't a gate valve be used for regulating?
No. Gate valves are designed to be either completely open or completely closed. Regulating flow is best done with a globe or plug valve, or certain kinds of ball valves. A gate valve left partially open will eventually wear down so that it can never be completely closed.
What are the basic components of a gate valve?
the gate and the valve.
What is the difference between a knife gate valve a gate valve?
A Knife Gate Valve is used to slice through sludge /sewerage and a gate is used fro normal positive shut off If you want to find the photo of Knife Gate Valve,you can enter to the link:http://www.kolinkcn.com/

Difference between globe valve and gate valve?
The Gate valve is the stop valve & the Globe valve is the fluid Regulating valve.

When is the Golden Gate Bridge open?
It doesn't close.
What does the gate valve's advantages?
The gate valve has NO advantages that I can easily think of. They are slow and clumsy to operate, they are prone to corrosion and they have a bad habit of breaking the shaft. If I had my way, I would replace every gate valve with a ball valve which is easier to use, easier to see if open or shut and far more reliable.

What is Forged steel gate valve flanged?
Forged steel gate valve flanged is just a gate valve which with a flange.
Why is it called a butterfly valve?
Because the inner area where the fluid moves has a gate which is shaped like a butterfliys wings. Passing through the centre of this gate is a rod which ends outside the valve where the handle is attached. When the gate is open it allows flow, when closed the gate seals off the valve stopping flow or if require can be partially turned to restrict flow
What type of simple machine is a gate?
A gate can be considered a lever simple machine, as it pivots around a point to open and close.
Gate valve manufacturer in India?
Specialityvalve is one of the biggest producer and supplier of Gate valve Manufacturer in India. Gate Valve is a control valve that either allows the fluid flow or stops it depending upon our use. It is a most common valve for water valve systems. It is a linear motion valve that starts or stops the flow. It got its name from the element sliding into the flow stream to provide shutoff, hence acting like a gate. Thus it is used either in the fully closed or fully open positions. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid. When the gate is fully opened it enables the gate valve to offer straightway flow with very little pressure drop. Gate Valves are also called as Sluice Gate Valve. Automated Gate Valve also exists which are either electric or pneumatic actuator, but as manual gate valve are cost effective hence it is affordable and as gate valves are used lesser. Gate valves should not be used for regulation or throttling of flow because accurate control is not possible. Components of Gate Valve ● Body ● Bonnet ● Body Seat ● Stem Nut ● Yoke Nut ● Stem ● Handwheel ● Gasket Working of Gate Valve The main three components of Gate Valve are: body, bonnet and stem When the handwheel is rotated which rotates the stem and due to it there is vertical movement of the gate via threads. They are considered multi-turn valve as it requires more than 360 degree to fully open the gate. When the gate is lifted from the flow path, it is open and when it returns it is closed and hence the flow is stopped.

What is the function of gate valve?
A gate valve is positive shut off and used for on of off . A globe valve is for throttling
