Integrating the use of fluid-dynamic components with pneumatic automation components is crucial for the construction of machines and tools

Many specific areas require advanced applications that need innovative technologies and components. The actual technical quality of the machines, instruments or devices set in a new and technologically successful context is determined by the single component integrated in a command, control and implementation system.

The fluid-dynamic components, so called because built to control and manage all types of liquid and gaseous fluids, also known as valves and solenoid valves are often inserted in a pneumatic or electro-pneumatic automation system.

The integrated use of valves and solenoid valves, which in most cases are 2 or 3-way, completes an automatic machine, a plant or a tool that, for their intrinsic functions, need control and management of liquid fluids other than compressed air, in addition to the movement through its actuators and solenoid valves for the relating control.

Today we can find examples of integration of fluid and pneumatic components, both serving each other, in many industries. We can easily find typical examples in Packaging, Textile, Sterilization or Pasteurization machinery, in Machine tools, in commercial Vehicles, in plastic injection Machines, food processing plants, etc.

Packaging:

With the proportional digital PRESSURE REGULATOR we can control the belt’s tension and the pressing force of an automatic labeling machine equipped with solenoid valves and pneumatic actuators for all the labeling process operations. Furthermore the application of a marking at the end of the line in wrapping and packaging equipment requires the use of 2/2 and 3/2 special solenoid valves for water, solvent or oil based inks. In addition we can say that high flow vacuum 2/2 and 3/2 solenoid valves with sizes ranging from 1/2” to 2” are essential to form containers and to create modified atmosphere for food packaging.

Textile:

Transport and movement automation requires the use of very reliable pneumatic components sometimes very fast and specific for each operation of the textile production process, from the yarn preparation to weaving and finishing. Within the production process sometimes there are applications where the requirements are for 2/2 high flow solenoid valves with response times under 10 milliseconds for the wire treatment during its preparation or launching the shuttle on the looms.

Sterilizers:

The systems and machines used for sterilization or pasteurization in the food or pharmaceutical industry use special 2/2 high vacuum and high temperature solenoid valves, incorporated into an automated transportation process for a treatment with often very sophisticated pneumatic components.
