Product Description

Axial flow check valve has the advantages of small flow resistance coefficient, low water hammer pressure, low noise, good flow performance and fast response speed. It is widely used in oil and natural gas long-distance pipelines, compressors and large-scale at the pump outlet. As a key part of the pipeline system, the performance and life of the check valve directly affect the safety of the pump unit and pipeline. Especially the instantaneous speed of the valve disc when the valve is closed directly affects the impact load of the valve disc on the valve seat, and affects the service life and reliability of the valve. When analyzing the dynamic performance of the axial flow check valve, the traditional test method often consumes a lot of time and money, which greatly increases the production cost of the product.

Product Features

1. The product consists of valve body, guide fluid, axial movement disc and spring parts. The product can effectively prevent the backflow of the medium. Make sure the pipes are safe.2. The valve body, valve disc, and tail vertebra are designed into streamlined channels, which have good fluid performance and minimize flow resistance and pressure.3. Using high-performance spring material HT/INCONELX-750, it has excellent corrosion resistance, oxidation resistance and excellent mechanical properties to ensure that the spring is in safe working condition and running state.4. Quiet operation, thereby eliminating noise and water hammer in the valve pipeline to ensure the safety of equipment and pipelines.5. The opening and closing response is quick, and the highly reliable pre-compression spring makes the valve disc respond quickly to the change of fluid pressure.6. The structure is compact and easy to install. It can be installed vertically or horizontally.7. The valve adopts alloy steel surfacing welding sealing surface, which is wear-resistant, corrosion-resistant and has a long service life.8. The pressure range of the valve is wide.
