For example, high pressure gas containers need to be tested once every two years while low pressure containers such as fire extinguishers are tested after every 5 or 10 years [4].
Do refrigerant bottles have a check valve?
They contain up to 50 lb of refrigerant. Disposable containers are designed so that they cannot be refilled. These cylinders use a one-way valve, also called a check valve. The one-way valve allows the refrigerant to flow only out of the container and prevents anything from going into the container.
