Use of PVC materials in vacuum systems
In the world of vacuum systems, material selection is critical to ensuring efficiency, durability and reliability. Among the various materials available, PVC (polyvinyl chloride) and UPVC (unplasticized polyvinyl chloride) have become popular choices, especially when it comes to plastic valve fittings.

Performance comparison of PVC materials and metal materials in valve fittings
When it comes to valve fittings, material selection can significantly impact performance, durability and cost-effectiveness. Two popular materials used in valve fittings are PVC (polyvinyl chloride) and UPVC (unplasticized polyvinyl chloride) as well as traditional metal materials.

Performance comparison of PVC and PPR materials in valve fittings
In pipeline and industrial applications, valve fitting material selection is critical. Two popular choices are PVC (polyvinyl chloride) and PPR (polypropylene random copolymer). Both materials have their unique advantages and applications, but how do they compare in terms of performance, especially when it comes to valve fittings?
