Check valve Application

Check valve refers to the opening and closing parts of the circular disc and by its own weight and media pressure to produce action to block the media flow back valve. Automatic valve class, also known as check valve, one-way valve, back-flow valve or isolation valve.

Check valve classification

By the structure: lifting check valve, swing check valve and butterfly check valve.

1) Lift check valve is divided into vertical check valve and horizontal check valve.

2) Swing check valve is divided into single, double and multi - flap type.

3) Butterfly check valve is straight-through type.

The above check valve in connection form can be divided into thread connection, flange connection, welding connection and clamping connection four.

Check valve characteristics

①To prevent media flow back.

②Prevent pump and drive motor reversal.

③Discharge container medium.

④Selection of more, a wide range of application.

⑤Large fluid resistance, poor sealing.
