Axial Flow Check Valve
The axial flow check valve is a type of check valve in which fluid flows along the axis direction. The valve seat features a disc-shaped structure with a low-resistance design, which effectively ensures steady flow, erosion resistance, noise reduction, vibration damping, and low resistance to backflow. It is widely used in pump outlets, long-distance pipelines, and municipal water supply systems. This check valve adopts an axial flow shuttle structure with a spring-loaded disc assembly that provides buffering and anti-vibration functions. When the fluid flows downstream, the valve disc opens, allowing the fluid to circulate through the axial flow passage. The spring buffers the impact between the valve disc and valve body. When the medium flows in reverse, the valve disc quickly closes, cutting off the backflow. This valve features silent operation and rapid response, making it ideal for preventing backflow and water hammer damage.

- The KOSEN series axial flow check valve features a streamlined Venturi port design and is available in sizes from 2 Inches to 48 Inches, with pressure ratings from ASME Class 150 through 2500 LB, as well as a wide range of body and trim materials to meet special application requirements.
- In the KOSEN axial flow check valve, the disc is the only moving part, minimizing internal wear. The configuration of the disc, seating, and body provides a streamlined flow path with a Venturi effect, reducing pressure loss to the lowest possible level. The compressed disc spring initiates valve closure as the flow slows down and provides a quick response to changes in flow velocity.
- These unique design features ensure an effective dynamic response under various flow deceleration conditions. This valve design can be used in a wide range of critical and demanding service applications, such as fast-reversing reciprocating compressors.
» The entire valve port geometry features a streamlined Venturi-shaped design. Both the body and seat are designed to accommodate medium flow efficiently, while the disc surface is fully rounded. In addition, the support frame at the valve outlet adopts a tapered structure. These design features ensure high flow efficiency and minimize pressure loss.
» As the inlet flow decreases, the disc responds immediately to limit medium backflow and prevent valve slamming. Due to the spring-loaded design, low-mass disc, and short travel distance, the disc can close as quickly as possible. At the moment of zero flow, the disc is fully closed.
» Under low-pressure conditions, the internal spring preload forces the disc tightly against the seat to achieve reliable sealing. Axial flow check valves can overcome the common problem of poor sealing performance experienced by conventional swing check valves under low-pressure conditions.
» Water hammer problems are effectively eliminated with this design because of the spring-loaded disc, which is properly sized for the specific application, combined with its low mass and short closing stroke. The spring initiates disc closure before water hammer effects can occur.
» The axial flow check valve can be installed in any position. Compared with conventional swing check valves, this provides customers with much greater installation flexibility.
» Axial flow check valves are available in both long-pattern and short-pattern designs.
» In an axial flow check valve, the disc is the only moving part, providing high operational reliability.
» Compared with a two-piece body design, the one-piece body structure offers better fire-safe performance because there is no potential external leakage path.
» Since the sealing surface is made of metal material, it is more resistant to scratches and damage caused by particles in the flowing medium compared with soft-seated sealing materials.
» The internal valve port geometry adopts a streamlined Venturi-shaped design to ensure minimal pressure loss. This energy-saving feature typically results in less than half the pressure drop of conventional check valve designs.
