RPV stands for Residual Pressure Valve, and it’s a vital component for maintaining positive pressure within a cylinder or tank. RPVs are considered safety devices because they prevent contaminants from entering the cylinder and interfering with the flow of CO2.
Maintaining Positive Pressure
Essentially, an RPV regulates pressure inside of the cylinder by keeping it just above the external atmospheric pressure. Since gas cylinders are often stored outdoors and exposed to changes in temperature and humidity, any fluctuations in the cylinder pressure could result in moisture or air contaminating the cylinder contents, leading to corrosion and other problems. Using an RPV prevents this from happening.
Preventing Backflow
Because the RPV is a one-way valve, CO2 (or any other substances) cannot backflow into the tank when the pressure drops. This is extremely important for maintaining CO2 purity in operations like cannabis extraction and beer production.
Safety Above All Else
Using an RPV ensures safe handling, storage, and operation of CO2 tanks by maintaining pressure and blocking contaminants, as interference from either can contribute to accidents and system downtime.
