It is a waterway component that is matched with the fire extinguishing devices ZDMS0.6/5S-YKS25, ZDMS0.6/5S-YKS30, and ZDMS0.6/10S-YKS35, as well as the high-flow nozzles and the end water testing device.

The opening and closing technology of "floating valve core" is adopted. Due to the uniqueness and scientific nature of the opening and closing principle, it opens and closes very quickly (it can be opened in 0.1 seconds), and has good sealing performance and is not easy to clog.

In terms of materials, except for the valve body which is made of brass, all other water-related components are made of flame-retardant high-strength engineering plastics. The reset spring is also set outside the medium, so it does not rust or scale.
