In addition to the functions of a general check valve, the axial flow check valve is also designed with shock-absorbing springs, which have the effects of noise reduction and shock absorption. It is convenient for on-site maintenance by users. The unique axial flow structure features low flow resistance, large flow rate and small external dimensions. It is the preferred valve for domestic and international oil and gas gathering and transportation pipeline systems, especially for the outlet of oil transfer pumps. It is applicable to pipeline systems for oil, gas, water slurry, etc., to prevent the backflow of the medium.
1. Single-unit structure, light weight, good rigidity, and easy to maintain.
2. The thrust of the spring enables the valve disc to handle the closed position even when used without the action of medium pressure.
3. The good support method ensures that the valve disc and seat can be well centered no matter what installation position the valve is in, so the valve can be installed at any Angle
4. The combination of the streamlined design of the valve sleeve shape and the streamlined design of the body cavity forms the streamlined flow passage of the axial flow check valve. Precise calculation and design ensure that the flow passage area is sufficient and consistent, with low pressure loss, stable flow state and no cavitation. When the medium flows, the valve stem generates negative pressure and spring thrust to return to its seat, and there is no direct impact of the medium on the back of the valve stem. Therefore, the axial flow check valve is a low-noise valve.
