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 a wafer 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.
Can you replace the insides of a gate valve?
Most certainly BUT it has to be replaced with the same type of disc and spline
What valve is the preferred valve to use in throttling a gate valve or globe valve?
Never ever use a Gate type of valve for throttling ONLY a globe pattern is designed for this purpose and a needle valve
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.
What type of valve should be used on the cold feed to a hot water vessel?
A gate 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.
Is the full bore applicable for gate valve or that's just for ball valve type?
For Ball valve only,as it gives more full bore flow,unlike wedge block,slow operating in Gate valve.
What are the basic components of a gate valve?
the gate and the valve.
What is Forged steel gate valve flanged?
Forged steel gate valve flanged is just a gate valve which with a flange.
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.
Is there an Open and close indicator for a gate valve?
Yes buy a RISING Stem type
