1-piece 1000WOG internal thread ball valve has the characteristics of anti-corrosion, strong anti-sulfurization ability, fire prevention, anti-static, good sealing performance, etc. It has a wide range of pressure and temperature, is available in full-bore and reduced-bore, and can be equipped with a variety of drive devices. It is an ideal valve choice for chemical, petroleum refining, natural gas extraction and transportation systems. When the medium stagnant in the cavity of the internal thread ball valve is pressurized due to temperature changes, the medium pressure pushes the valve seat away from the ball to achieve the effect of automatic pressure relief. After the pressure relief, the valve seat automatically resets.
