Abstract

This item is a valve for refrigeration and air conditioning, and is an essential item when performing cycles such as cooling and heating with a refrigerant. Although there are various refrigerants in the world, this item is made entirely of iron and can also be used with the natural refrigerants (ammonia, carbon dioxide) that are currently attracting the most attention. In addition, the main body (body) adopts a forged product of S45C material, realizes a design pressure of 5.2 Mpa, and can also handle high-pressure refrigerants. In the future, it is predicted that higher-pressure refrigerants with less environmental impact will be created from the perspective of environmental protection. This item is a valve that you can use with confidence even in the era of high-pressure refrigerants.
