The use of pressure reducers with different application fields.
Gnali Bocia has refined the features of pressure reducers over time in order to obtain highly efficient components suitable for many different purposes.
Pressure reducers are extremely versatile components for many fields of application. Gnali Bocia has been able to refine these components in order to adapt them for the use with a range of fluids, each completely different from the other. Both gas and liquid elements such as water flow through these components. Although it may seem obvious, the design of pressure reducers can be extremely different depending on what is flowing through it.
In the engineering field, and indeed, schematically, pressure reducers are referred to as thermal expansion valves. Their purpose is to reduce the pressure of the fluid flowing through it from a given value at the inlet to a lower value at the outlet. This reduction of work supports a transformation process called “isenthalpic” occurring inside the pressure reducer, which means that the total energy transported by the flow remains practically the same as it passes through the pressure reducer.
The difference between the upstream and downstream pressures consequently translates into an energy contribution produced by the viscous resistance of the flow on the wall of the pressure reducer.
In some cases, particularly as concerns gas, the viscous resistance can lead to an increase in temperature which is proportional to the viscous resistance itself.
