Is gate valve used for throttling?
Never. Throttling will erode the valve seat and then the valve will never shut off completely.
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 a valve grinder used for?
There are many things that a valve grinder is used for. Typically, a valve grinder is used for helping a fuel air mixture to come in and to exhaust the burned gasses.
What is SDV valve?
Shut Down Valve- used in ON/OFF position only.
Why is a throttling valve called an expansion valve?
It is not.. A globe , needle , ball valve are used for throttling For expansion either a shock absorber , diaphragm tank or air chamber are used to allow for expansion
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
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/
What type of valve is used in a peanut butter factory ball or gate or globe or gate?
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.
How do you calculate torque of a gate valve?
how to calculate gate valve torgue. What is the torgue required for 1100NB gate vave used for 3kg/cm2 steam line
What is the definition of sluice valve?
It can be defined as followed. Valve in sliding water gate.
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 type of valve should be used on the cold feed to a hot water vessel?
A gate valve

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 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 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
