The operation of a pressure reducing valve is based on a simple but effective principle. PRVs utilize a spring-loaded diaphragm that senses the downstream pressure. When the downstream pressure rises above a preset level, the valve reacts by closing partially or completely, thereby reducing the pressure entering the system. Conversely, if the downstream pressure drops too low, the valve opens more to allow additional fluid flow, maintaining the desired pressure. This feedback mechanism ensures that the system operates efficiently and safely.

A blood pressure regulator, also known as a blood pressure monitor, is a device that measures the pressure of blood in the arteries. This measurement is typically expressed in millimeters of mercury (mmHg) and consists of two numbers – the systolic pressure and the diastolic pressure. The systolic pressure is the higher number and represents the pressure in the arteries when the heart beats, while the diastolic pressure is the lower number and represents the pressure in the arteries when the heart is at rest between beats.
