Classification:
According to its structure and installed methods Check valve can be divided into:
1.Swing Check Valve: Swing check valve disc is cylindrical disk-shape, around the seat channel axis to do rotational movement, due to inner channel is the streamline, the flow resistance is smaller than the lift check valve, apply to the low flow rate and seldom flow changes large-caliber occasions, but it should not be used for pulsatile flow, its sealing performance is less than lift type. Swing Check Valve is devided into single disc, double disc, multi disc. These three types are mainly according to valve diameter, for the purpose to prevent the media stopping flow or reflux, reducing the hydraulic compact.

2.Lift Check Valve: disc slides along the body vertical axis, lift check valve can only be installed in horizontal pipelines, the high-pressure small-diameter check valve upper disc uses ball. Lift-type check valve body shape is the same with globe valve (commonly used to the globe valve), so its flow resistant coefficient is larger. its structure is similar to globe valves, body and disc are the same with globe valve. upper disc and lower bonnet have guided sleeve, the disc guided sleeve can freely lift, when the medium downstream, the disc opens by media thrust, when the media stopped-flow, the disc relies on self-vertical landing on the seat, affected as preventing media backwash. Straight-through lift check valve inlet and outlet media channel direction is perpendicular to seat channels; vertical lift-type check valve, its media inlet and outlet channel direction is the same with the valve seat passage, its flow resistance is smaller than the straight-through type.
