Check valve creates the metal-to-metal seal by the pressure of the medium, the more the pressure is, the better the sealing effect is. Anytime the valve chamber can bear the pressure of the pipeline. The sealing face between valve core and valve body is welded with hard alloy with good abrasion resistance and anti-scour, the valve core is made of sulfide-resistance steel and the others adopts the process of hardness limit so the valve is able to be used in H2S condition.
2. Main Technical Parameters:
3. Features:
(1). Sealing is energized by flow fluid pressure, sealing performance gets better while pressure increasing.
(2). Hard-faced sealing surface and sulfur-resistant core material assure fine performance of wear-resistant and corrosion-resistant.
(3). Integral forged body with fine mechanical properties.
(4). Check valve shall be hydro tested prior to delivery for sale performance.
