Oxygen service valves are required to meet high safety standards due to the highly combustible nature of oxygen, which can lead to severe accidents such as valve burning or explosion during the valve's operation. The valve stem sealing packing, being a critical component of the valve's operation, is particularly important for its sealing and reliability. The packing set is a specialized sealing packing designed and manufactured for use in oxygen service valves.
