Complaint
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.
(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.

Application | Check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in the pipeline. |
Structure | Swing check valve is also called one-way valve or check valve, its function is to prevent the medium in the pipeline from flowing back. The valve that opens or closes on its own by the flow and force of the medium to prevent the medium from flowing back is called a check valve. |
