Valves And Their Importance In The Industry




Within the universe of one of important thing that is used an installation, they are Gate Valve. When you think about them, the following basic questions arise:

  • What is the valve?
  • Why should you use it?
  • When should its use be made present?
  • How do you install it?
  • Where should it be placed?
  • Who regulates its design, manufacture, standards, materials, installation, pressure, temperature, etc.?

These questions will be answered briefly but offering the means to delve into each subtopic. Let us begin.

What is the valve?

You understand the mechanism as a set of elements that lead to an end through the transformation of the input energy they receive non slam check valve. These elements can be mechanical, electrical, electronic, pneumatic, etc. resulting in many valve types.

Why and when should you use them?

Some of the causes that lead you to require the use of a valve could be the following:

  • There is interest in that the inflow to equipment can be closed or opened in time.
  • A certain process requires that the fluid that enters is variable according to certain conditions.
  • The entry and exit speed must be different between the two points.
  • You require having absence of flow in some parts of the system to give maintenance or others.
  • You want to increase or decrease the pressure between two points.

However, the main basis is the variability in the state of the flow entering and leaving the system.

You must use them when variable conditions are required over time and related to the fluid that we handle in the system. “

How is a valve installed, and where should it be placed?

The installation of a valve is variable and depends on the type of valve. Each supplier has its technical specifications that guarantee the correct installation and operation of these instruments. It is correct to seek advice and leave the installation of valves in the hands of someone trained. However, some general considerations will be described below:

Some valves in your installation will require the use of flanges, while others may be welded. As a general criterion, a valve being a control element must not be installed where control cannot be exercised. That is, if you install the valve in an inaccessible place where no one can manipulate it, then the control you have over your process will be restricted by the location of the valve. Another element to consider is the maintenance or future replacement of the valve. If you leave the valve fully fixed without the possibility of being removed, you will be limiting maintenance work and process improvement, causing more problems than solutions.

Considering the technical specifications of the valve will prevent the instrument from being damaged prematurely, respecting the safety and health regulations also contributes to the correct installation and operation of the valve. You must make sure that before starting the valve, its assembly is correct; this means that the shafts are perfectly aligned, otherwise it may cause serious mechanical problems in it.
