Product Overview

Axial flow check valve has the function of general check valve, there are shock-absorbing springs, with muffling and shock-absorbing effect. Convenient for users to overhaul the site, the unique axial flow structure has a small flow resistance, large flow, small external dimensions, etc., can be used in oil and gas gathering and transmission pipeline network, oil pump outlet, suitable for oil, gas, water, slurry and other pipeline systems, to prevent the medium from backflow use.

Structural Features

Axial check valve products by the valve body, fluid conductor, axial movement valve flap and spring components, can effectively prevent the media backflow. Ensure pipeline safety, the valve body, valve flap, tailbone designed into a streamlined channel, fluid performance, limit the reduction of flow resistance and pressure, the use of high-performance spring materials, corrosion-resistant performance, oxidation-resistant mechanical properties, to ensure that the spring long-term working conditions, the operating condition.


Axial flow check valve silent operation, eliminating noise and water hammer in the valve pipeline to ensure the safety of equipment and pipeline, open and close the response quickly, reliable pre-pressure spring so that the valve flap on the fluid pressure changes in the rapid response, compact structure, easy to install, vertical, horizontal installation can be used, the use of alloy steel surfacing sealing surface, wear-resistant, corrosion-resistant, long service life, the pressure range of the relatively wide.
