The inlet and outlet of ceramic star valves adopt irregular anti seize design while protecting the valve core. The only ceramic star valves on the market have simple vertical inlet designs, which cannot achieve anti seize design and cannot protect the valve core. Moreover, the design of ceramic star valves can prevent blockage, jamming, and sticking, which significantly improves the equipment's ability to prevent raw materials from sticking.
