Though valves are used for a variety of purposes, gate valve is basically used to either open or shut the duct of the pipes completely. It cannot be used to regulate the flow of water or liquid. Partial opening of the valves can cause serious damages to the pipes. One of the greatest advantages of these valves is that it helps to limit the pressure in the pipes while the valves are opened.

However, there are valves which can be used to regulate the flow of liquid in a linear manner. These valves are quite expensive compared to the normal valves and it includes more complex functions. It is also known to have less durability. Most of these valves can be bought easily from online stores today.
