It is worthwhile to point out that this valve can meet the requirements of anti-sulfuration stress cracking under sulfuration environment, which has been approved by domestic and foreign users through their use for many years. ln according to the requirements of anti+sulfuration stress cracking, design, material selection, manufacture and testing arc conducted by strictly referring to relevant standards of American Corrosion Engineers Association. In order to meet. the strict requirements on anti-sulfuration stress cracking in some occasions, our company has adopted a set of measures from design, material selection, manufacture, testing to surface treatrrient.

This valve chooses polymerized substance as seal material and has good seal performance within wider ternperature and pressure range. Valve is made of a wide range of material, with complete specifications and pressures. Full latus rectum and mouth-reducing types arc all available. It is applied to flow system of chemical engineering, oil refining and oil gas exploitation.
