Temperature limit table for valve body material
2014-08-13 Number of attention:
Valve body material selection should be based on the nature of the medium, working temperature and flow to determine (whether there are particles, two-phase flow, etc.). Under normal circumstances, users are required to put forward valve main material. Especially for special working conditions or harsh working conditions. In most cases, valve body material is the same as pipeline material or slightly higher than pipeline material.
