How are pressure controllers classified?

Pressure controllers are classified based on the levels of pressure they are designed to manage within a system. The classification into high and low pressure is essential because different systems—such as boilers, HVAC systems, and pipelines—operate under varying pressure conditions. Each type of pressure controller is tailored to function optimally within its specified pressure range.

High-pressure controllers are utilized in systems that operate at elevated pressures, ensuring that the pressure remains within a safe and efficient range to prevent any risk of overpressure situations that could lead to equipment failure or safety hazards. Conversely, low-pressure controllers are designed for systems with lower operational pressures, helping to maintain these conditions effectively.

This classification is crucial for proper system design and safety. It ensures that the appropriate controller is selected for the application, enhancing both the efficiency and reliability of pressure management in various operations. Other classifications, such as temperature, flow, or voltage, do not specifically pertain to pressure control and serve different functions related to those parameters.
