JIS 10K Cast Iron Gate valve
JIS 10K cast iron gate valve adopts reinforced thick cast iron body to upgrade pressure bearing capacity compared with 5K low pressure type. It is fitted with bronze disc and seat pair to achieve abrasion resistance and tight sealing during frequent on-off operation.
Overview
Application: It is widely applied to medium-pressure ballast water, cooling water and drainage pipelines on various ships and marine vessels. Suitable for general industrial piping systems that only require complete cut-off without flow throttling regulation.
