What is a Constant Pressure Expansion Valve?

The constant pressure expansion valve, also known as the automatic expansion valve, is a device used to control and stabilize the pressure of fluids, primarily in hydraulic systems. The main purpose of this valve is to maintain a predetermined pressure to ensure the system’s safety and optimize its performance.

It is a critical component in various systems including refrigeration units, air conditioning systems, and more. This device is integrated into these systems to prevent potential mishaps due to pressure fluctuations, thus securing the efficiency and longevity of the apparatus.

Working Principle of a Constant Pressure Expansion Valve

The functioning of a constant pressure expansion valve is founded on a set of mechanized actions that precisely control the pressure and temperature of the fluid passing through it.

The valve operates by using a complex yet efficient mechanism that involves a sensor, which monitors the existing conditions of the fluid. According to the sensor’s readings, the valve adjusts its opening to regulate the flow, hence maintaining a consistent pressure.

How to Install a Constant Pressure Expansion Valve

Installation of a constant pressure expansion valve is a step-by-step process that requires meticulous attention to detail to ensure it functions correctly and safely.
