Valves are a key component in the hydraulic field and a key component in water supply, civil engineering and industrial plant engineering that can intercept or regulate the flow of materials within the pipeline.

Valves are key components of the hydraulic system and key components for water supply, civil and industrial plant engineering to intercept or regulate the flow of materials within the pipe.
An example of a valve-
Ensure a specific level of pressure or flow-
It\'s a simple faucet in the house.
There are a wide variety of valves-The following are the main common types: ball valves: This valve is best suited to intercept and manage the flow in the pipe.
There are usually carbon steel ball valves or stainless steel ball valves.
Butterfly Valves: they rotate around the axis of the tube;
It is usually used for water systems, not for other materials to flow.
Stop valves: they can be used as a channel for closing valves to balance substances.
The three decisive factors that ensure that everything works properly constitute each valve: a body, a shutter of the control element.
The body contains the shutter and allows the connection of the tube in which the material flows, as well as the connection to the control element.
The shutter intercepts the flow while the control element-
Whether it\'s manual, electric or magnetic
Operate the shutter.
The anatomy of the valve reminds a \"Chinese Box\": each element is connected to or contains another element, and it is precisely because of this synchronous gear that the valve performs its action.
How to distinguish valves?
First of all, in order to evaluate the difference between valves, it is necessary to start with the shape of the body: Butterfly, sphere, mushroom, clip, Ball, needle, door, Fuse, rotation and exhaust.
Next to the shape of the structure, it is important to understand the type of drive connected to the components that determine the movement between the plug and the main body for understanding how the valve works: there are actuators with electronic control, the linear motion of the shutter is determined by the magnetic field;
There is an electric control actuator, which causes a straight or rotating motion of the shutter by the motor;
There is a pneumatic control executive mechanism, which is determined by the pneumatic piston;
An executive mechanism with hydraulic control, whose shutter movement is connected to the energy of the hydraulic flow;
There is a constant temperature control in which the shutter moves through thermal expansion.
The drive can also be Manual due to the handwheel valve or lever.
Finally, the type of application distinguishes valves.
It can be a closed-
Turn off one if they are only used to monitor traffic
In this case, it must be kept or turned on or off.
When the function of the valve is to control the flow rate, they are used in the middle position, thereby adjusting the flow rate or pressure of the material.
The exhaust valve allows the removal of air, while the safety valve promotes fluid leakage when the flow pressure is too high.
The check valve allows the material to pass in one direction, indicated by an arrow on the valve housing.
Therefore, all valves have specific features and are suitable for specific functions and applications.
This means that if carbon steel ball valves or stainless steel ball valves are commonly used, you should check the valves you are interested in to see if they are the best fit for the work you are going to do.
