Pressure controllers are devices designed to automatically maintain a specified level of pressure of the working medium (gas or liquid) in various industrial systems. They are widely used in gas supply, heating systems, pneumatic installations, and other engineering networks.
The operation of pressure controllers is based on the balance of forces between:
When pressure after controller drops below the set value, spring expands, opening the valve to increase the flow of the medium. If the pressure rises above the norm, the spring compresses, closing the valve and reducing the flow. This achieves a balance between the input and output pressure.
