Fire butterfly valve

This series of butterfly valves adopts a midline design. The main structure of the valve is composed of valve body, valve disc, valve seat, valve stem and transmission operating mechanism. The valve seat adopts a detachable structure. The transmission mechanism is divided into three types: handle type, worm gear type and signal type. It is suitable for water pipes in fire sprinkler systems for throttling or regulating flow. The signal valve is equipped with a signal switch at the switch position of the worm gear, which is suitable for water pipes in automatic fire sprinkler systems.

    Features


    The valve seat adopts a detachable design for easy on-site maintenance, and adopts a full-flow design, which is not easily affected by impurities. The "O"-shaped sealing lines at both ends allow the pipeline to be installed without additional gaskets and maintain reliable sealing, and different materials can be selected according to different usage requirements.


    The shaft pin adopts a pull-out pin structure, which can tightly combine the valve disc and the valve shaft together without loosening, weakening the strength of the shaft, and has good interchangeability.


    The operating structure is flexible to choose, and different rotating devices such as handles and worm gears can be configured according to customer needs. The worm gear can also be equipped with a signal device at the same time.
