Note: 1.H74opposite-clamp lift check valve, water hammer pressure is small, the valve stroke is short, the valve spring is lightweight, closing aid, valve closing speed.

2short length structure, small volume, light weight, as the valve installation transport storage to provide a great convenience, saving a large amount of material and reduce the cost.

3 fluid resistance is larger, fluid drag coefficient 6.4--2.8

4small valve opening pressure, in a very small pressure difference can be completely open.

The 5 valve is an integral structure, simple and compact structure, small impact force of valve switch, the water hammer pressure is small, long service life, high reliability.

6 this series check valve has two structural length, using the series of low price, but check valve and pipe flange between straight and may have to take a standard connection pads, if a long series of check valve, configurable standard flange gasket.

7 in order to facilitate the users, the company can provide configuration on the clamp check valve sets of the flange, gasket, bolt nuts, but users need to quote.
