Anti-sulfur ball valve has met the cracking requirement of anti-sulfur stress under the sulfuration environment. Inner parts adopt nickel plated or #16 materials and shrouding chooses polymer as sealing material that is applicable for wide range of temperature and pressure. Materials choosing for design and test are strictly in accordance with NACE (National Association of Corrosion Engineer USA). It has strong ability of corrosive-resistance and anti-sulfuration, stable sealing and good performance of fire-resistance and electrostatic prevention. With complete specification, pressure, full bore and reducer diameter, this valve is an ideal one in flow system for chemical oil refining, oil gas exploitation and others.
