A check valve is intended to prevent a medium flow direction in a process system. Depending on the operating pressure, two types are distinguished: low-pressure and high-pressure. An oxygen check valve as per GOST 12.2.052-81 “Occupational Safety Standards System” shall be made of brass and copper-containing materials.
The check valve serves as a reliable protection of the system against pneumatic overflow, which allows the equipment to operate smoothly.
