Check Valve

The working principle of the check valve is to use the automatic opening and closing action of the valve disc to prevent the backflow of fluid. When the medium flows normally, the valve disc will automatically open under the action of fluid pressure, so that the medium can pass smoothly; When the medium pressure or flow rate is reduced to a certain value, the valve disc will automatically close to prevent the backflow of the medium.

• Good sealing performance: the disc and seat of the check valve are usually made of metal or a combination of metal and non-metal materials, which have good sealing performance and can ensure that the medium does not leak.

• Low fluid resistance: The flow path design of the check valve is reasonable, and the resistance of the fluid passing is small, which can reduce the energy consumption.

• Automatic opening and closing: the disc of the check valve can be automatically opened and closed according to the flow of the medium, without manual operation, easy to use.

• Wide range of application: The check valve is suitable for various media and temperature ranges, and can meet the needs of different working conditions.
