The role of pressure stabilizers in a gas system

Pressure stabilizers for gas: what they are, what functions they have, what are the fundamental components.

The systems for the conveyance and conduction of gases are essential for various types of domestic and civil users. The use of pressure stabilizers, in this field, is an essential requirement for the proper functioning of the system: all phases, from design to assembly, require care and attention, thus avoiding damage or failures that they may cause. Not only economic or time losses, but also problems connected with the safety of buildings and the people in contact with them.

What is a gas pressure stabilizer?

A gas pressure stabilizer is a fundamental component of the system that allows the inlet pressure to be reduced to a lower value, allowing it to function correctly. In particular, within the Gnali Bocia catalog, there are two types of stabilizers based on pressure:

•  PRESSURE STABILIZER - P1: 400-500 -> the inlet pressure is equal to 400-500 mbar while the outlet pressure (P2) is equal to about 16-60 mbar.
•  PRESSURE STABILIZER - P2: 60-100 -> the inlet pressure is equal to 60-100 mbar while the outlet pressure (P2) is equal to about 13.7-30 mbar.


Main components of gas pressure stabilizers

Pressure stabilizers are devices made up of many different components. In particular, a fundamental role is played by the shutter and the adjustment spring which are the elements that allow to reduce and regulate the pressure between inlet and outlet. There are a number of other components that serve both to constitute the main body of the stabilizers (lids and caps) and to allow the shutter to perform its function correctly (such as, for example, pins, membranes, sealing elements).

The F and SF version

The gas pressure stabilizers can be produced in two different versions regardless of the pressure they have to manage. In fact, a fundamental role is played by the filter:
- F: is the version characterized by the presence of a filter;
- SF: it is the version that is not characterized by the presence of a filter.
As regards the second version, it is necessary, at the time of installation, that a filter is placed "upstream" of the device in such a way that the mesh size is equal, as a maximum value, to 1.5 mm and not allows the passage of a gauge of 1 mm.
Based on the fundamental role played by the stabilizers both for operation and for safety, it is necessary that the installation and calibration operations are carried out by specialized technical personnel. In fact, in addition to the deposition of a filter, it is necessary to correctly evaluate the system "upstream" of the device to prevent problems such as overpressure or corrosion from deteriorating it, reducing its effectiveness and operating efficiency.
