Only be used to single-track water of round or square water outlet, it has advantage of strict structure, good reliability and operate need not the force of people. Motive power of start and stop come from the pressure of water. When the inside pressure greater than outside, the flap valve will open, conversely, it will close.

 

The nature of flap valve:

 

Nominal pressure: 0.1MPa-1.0MPa

Applicable media: water, river water, seawater, living water, industrial sewage.

Applicable temperature: <50°C

 

Applicable scope:

water conservancy system, municipal wastewater, flood control works, sewage treatment plant, waterworks and so on.

 

The specification and category:

The specification of flap valve is divided into round and square two kinds, it can be designed and produced depend on the form of the water outlet.

The flap valve has two categories: hollow floating plate shape and flat plate shap.
