Burner valve Works

     Pneumatic means, or other means for driving the upper end of the stem, the output torque transmitted to the ball Bbq Gas Valve, cause it to rotate 90 °, the sphere flow path coinciding with the center line of the burner valve flow path, a double doctor blade superhard seal burner valve opening action is completed, whereas the vertical, so that complete closure of the burner valve action, closed clockwise or counterclockwise turn. When the ambient temperature, the high-titanium spring preload sulfur-free flexible graphite sealing Gas Burner Safety Valve surface expansion; high temperature, high sulfur-free flexible graphite titanium expansion itself, a seal between the Gas Top Burner Valve and the burner valve seat. Ball seat and seal sealing surface at low pressure, by spring preload makes sealing surface; at high pressures, so that under the action of the spring preload and media pressure, both sealing surface.
