    Product Advantage

    1. F4: German standard for gate valve performance, component material, generally we mainly refer to its structural length regulations.

    2. Bolted Bonnet: Indicates that the bonnet is bolted to the valve body.

    3. Rising Stem: Indicates that the valve stem rises and falls when operated, opening and closing the fluid passage, providing an indication of the valve position (open or closed).

    4. Body Bonnet Material: GGG50 Ductile Iron

    Advantages of gate valve:

    1) Small fluid resistance;

    2) Small torque required for opening and closing;

    3) It can be used on the ring pipeline where the medium flows in two directions, that is to say, the flow direction of the medium is not restricted;

    4) When fully opened, The sealing surface is eroded by the working medium and is smaller than the globe valve。5) The shape is relatively simple, and the manufacturing process is good.

    6) The structure length is relatively small. Usually, the pipeline with a nominal size larger than DN50 is used as the device to cut off the medium

    It is used as a cutoff and adjusting equipment for the various water supply and drainage pepeline in building ,chemial ,medicine,textile,ship and other  industries.  Zhongfa valve can offer OEM &ODM gate valves and parts in China.Zhongfa valve's philosophy is to seek for high quality products with optimal service with the most ecmonical price.
