Product Description
High pressure hard sealed ball valve can be selected when the temperature is higher than 250 ℃. The materials of valves can be selected according to the needs of users. In general, the following points should be paid attention to in the material selection of hard sealed high-pressure ball valves: 1. In high temperature environment, stainless steel non sluggish ball valves should be selected. Such high temperature is generally 100 ° C to 200 ° C. The sealing material is usually ppl, the valve body material can be WCB, the valve rod material should be stainless steel iron, and the ball material can be 201. 2. For ball valves with operating temperature between 250 ℃ and 400 ℃, it is best to choose materials with good sealing effect, and usually choose hard sealed high-pressure ball valves.
