Structure features:

1, It is short in face to face dimensions, being 1/4-1/8 times that of traditional flange type check valve.
2, It is impact in volume size and light in weight of about 1/4-1/20 times that of traditional flange type check valve.
3, The disc closes quickly with less water hammer pressure.
4, It is convenient in installation, being available for use on level or vertical pipeline.

5, Flow passage is fluent with flow resistance.
6, It acts sensitively with good sealing effect.
7, Disc travel is short with less impact force caused by valve closing.
8, It is impact in integral structure with nice outline view.
9, It is longer for service life with high reliability.
