The fire signal Grooved butterfly valves has the advantages of simple structure, reliable sealing, light opening, long service life and convenient maintenance. Therefore, it is widely used in various pipelines of water supply and drainage, building fire protection, etc., especially in fire protection pipelines. The signal valve can clearly display the valve switch state, and has an intuitive, clear and reliable reflection of the working state in the fire protection system, so it is widely and widely applied to the fire protection system.
