  • Gas flat gate valve product description

    Gas flat gate valve has triple sealing protection measures, its superior performance is mainly used for city gas pipeline, natural gas pipeline, valve seat and packing use sealing grease, play the role of emergency sealing and lubrication.Gas flat gate valve products are characterized by simple structure, reliable sealing, small switching torque, long service life and the ability to clean dirt in the chamber.The gas flat gate valve is equipped with a release valve to let off the remaining gas in the pipeline during maintenance.

  • Gas flat gate valve product structure characteristics


  • 1. The valve seat of the gas plate gate valve is of the floating seat structure with o-row sealing ring and pre-tightening force, so that the inlet and outlet of the plate gate valve are sealed in both directions, and the opening and closing torque of this structure is only 1/2 of that of ordinary valve, which can open and close the valve easily.


    2. PTFE is embedded in the sealing surface of gas plate gate valve seat, which has the function of PTFE double sealing to metal and metal to metal, PTFE sealing surface can remove the dirt of gate at the same time.


    3, gas flat gate valve with self-sealing capacity of the packing structure, no need to adjust often, open and close

    is very light, and reliable sealing, stuffing box with high quality auxiliary seal injection structure, sealing performance is absolutely reliable, truly achieve zero leakage, solve the general valve packing is the most prone to leakage defects.


    4. When the gate valve of gas plate is closed, it can automatically discharge the high pressure in the inner chamber to ensure the safety of use.


    5. Whether the gate of gas plate gate valve is fully open or fully closed, it is always consistent with the sealing surface, which is protected from direct erosion by the medium, thus extending its service life.


    6. The gas flat gate valve adopts a closed gear rotating opening and closing indicating mechanism, which can  clearly reflect the opening and closing situation of the valve for a long time.
