The hydraulic system is incomplete without pressure control valve. This makes them an essential part of every hydraulic device. There are a number of functions which are performed by this device. The upper pressure is not only maintained but these devices also ensure that a particular pressure is maintained in a certain part of device or circuit to which it is associated. The two main types are open and closed valves. Both are used in various industrial applications. An example of the closed valve is unloading and that of the open valve is a relief. The concept of this appliance is not simple and thermodynamics are applied while these are manufactured. Basic of the device are as follows:

Cracking pressure

There are several other terms which are related to cracking pressure or without which the term cannot be explained. Some important definitions are as follows:

  • The type of pressure at which for the first time pressure control valve allows the fluid passage is known as cracking pressure.
  • The point at which the valve bypasses the full flow is known as full flow pressure.
  • The difference between cracking pressure and full flow is known as pressure override

The device is both auto and operator driven. Pressure override isn’t a problem in some issues but most of the time it is. Pressure override can lead to power wastage and this is its greatest disadvantage.

How pressure control valve works

The working of pressure control valve is just like an electrical circuit. The main concept is to save the circuit. Till the amperage of the circuit is below fuse value everything is fine. When the amperage tries to exceed or actually exceed the fuse value it blows. Though it destroys itself but saves the circuit at the same time. The pressure control valve on the other hand ensures that the best alternative path is given to the fluid if hydraulic system pressure reaches the maximum point. For every hydraulic system pressure control valve is a very important as it makes sure that the system is never damaged. Due to the flow of fluid when the pressure reaches the maximum level pressure control valve opens to bypass the fluid. The process continues till the pressure falls. Most of the pressure control valves are automatic in nature and therefore no human intervention is required. There are many types of pressure control valves in the market and depending upon the configurations work for different hydraulic systems.

Some benefits of control valves

To understand the operation of pressure control valves in full some advantages of the device are as follows:

  • The flow of fluid is human independent. No operator is required to control the process and hence it is one of the best ways to maintain system pressure.
  • Both time and effort of the users are The deployment of pressure control valve is very simple and easy to perform. There is no need of any plumber or technical assistance.
  • The pressure control valves are also power savers as they neither waste resource nor let the system do that. Efficient working is a big plus when it comes to these devices.
