Axial flow check valve can satisfy different application conditions with greater reliability and less maintenance and operation cost. After years of application, the axial flow check valve has excellently proven its reliability and ability to meet a variety of working conditions, and is used in many strict occasions.

Axial flow check valve body cavity surface, deflector cover, valve flap and other flow surfaces should have streamline shape, with rounded front and rear pointed. The fluid exhibits predominantly laminar flow at its surface with little or no turbulence.

In addition to the functions of a general check valve, the axial flow check valve is also designed with a shock-absorbing spring, and its combined seat sealing structure with hard seal and soft seal has the effect of noise reduction and shock absorption, which is convenient for users to overhaul on site. The unique axial-flow shuttle structure has the advantages of small flow resistance, large flow coefficient, and small size. It is suitable for pipeline systems such as oil, gas, water slurry and acidic corrosive media containing H2S+CO2, and the control medium is used in countercurrent.

The axial flow check valve adopts an axial flow shuttle structure in structure, and its valve disc is equipped with a buffer damping spring. When the medium flows downstream, the valve disc opens, the medium circulates through the axial flow channel of the valve body, and the medium is pushed open. When the valve disc is opened, the spring plays a buffering effect, which avoids the impact and vibration between the valve disc and the valve body when the ordinary check valve is opened. When the medium flows in the reverse direction, the valve flap is quickly closed, and the valve flap and the valve seat are closely fitted to prevent the reverse flow of the medium. The combined hard seal and soft seal valve seat structure can effectively reduce the impact noise when the valve disc and the valve seat are fitted. This type of check valve is an ideal product for fluid gathering and transportation network to prevent medium backflow and eliminate noise and vibration.
