HH46X, HH48X, HH49X quiet slow stop check valve series products can be used in clean water, sewage, sea water and other media of the drainpipe, not only can prevent the backflow of media, but also can effectively limit the destructive water hammer, to ensure the safety of the use of pipelines.It has novel structure, small volume, light weight, small fluid resistance, reliable sealing, smooth opening and closing, wear resistance, long service life, oil pressure, slow closing is not affected by the medium, has better energy-saving effect and other characteristics.
1. The structure length is short, and its structure length is only 1 / 4 ~ 1 / 8 of the traditional flange check valve
2. Small volume, light weight, its weight is only 1 / 4 ~ 1 / 20 of the traditional micro resistance slow closing check valve
3. The valve disc closes quickly and the water hammer pressure is small
4. Horizontal or vertical pipes can be used and installed conveniently
5. The flow channel is unobstructed and the fluid resistance is small
6. Sensitive action and good sealing performance
7. The stroke of valve disc is short and the impact force of closing valve is small
8. Overall structure, simple and compact, beautiful appearance
9. Long service life and high reliability
