Long distance pipeline gas ball valve

' Long-distance pipeline gas ball valve
b, ' The pipeline ball valve series is based on the needs of users. In order to meet the requirements of resisting sulfide stress cracking in a vulcanized environment, we design, select materials, manufacture, test, surface treatment and Painting is strictly carried out in accordance with the relevant standards of the American Society of Corrosion Engineers.
b, ' This pipeline ball valve series not only has a wide range of materials, but also the internal parts are made of nickel-plated surface or 3-material, and the sealing rings are made of special polymer materials. Alloy steel valves are not only anti-corrosion, anti-sulfurization, strong, fireproof, static-discharging, and have good sealing performance, they are applicable to a wide range of pressure and temperature, are available in full diameter and reduced diameter, and can be equipped with a variety of driving devices. They are ideal for chemical and petroleum refining industries. Control, natural gas extraction and transportation systems are separated from each other by valve selection.
b, ' Main functions:
b, ' When the stagnant medium in the middle cavity of the pipeline ball valve hesitates due to temperature changes and increases abnormally, the medium pressure pushes the valve seat away from the ball to achieve the effect of automatic pressure relief. The rear valve seat automatically resets.
