What is the primary purpose of a pressure reducing valve in a medical gas system?

The primary purpose of a pressure reducing valve in a medical gas system is to decrease the pressure to a set level, which is often around 50 psi. This is essential for ensuring that gases delivered to patients are at a safe and manageable pressure, as high-pressure gas could pose risks of injury or equipment damage. A properly functioning pressure reducing valve helps maintain the integrity of the gas delivery system, which is crucial for patient safety and the effective operation of medical devices.

In this context, having a pressure set at approximately 50 psi allows the medical equipment to operate efficiently without overwhelming the devices or endangering patients through excessive pressure. Maintaining this lower pressure also facilitates consistent flow rates and ensures that gas purity is preserved throughout the delivery process, as no contaminants are drawn into the system from external sources.
