Structural characteristics of H72H high-pressure clamp check valve:

1. The structure and length are short, and its structural length is only 1/4-1/8 of that of traditional flange check valves;	6. Sensitive action and good sealing performance;
2. Small in size and light in weight, its weight is only 1/4-1/20 of traditional flange check valves	7. Short valve disc stroke and low impact force when closing the valve;
3. The valve disc closes quickly and the water hammer pressure is low;	8. Overall structure, simple and compact, beautiful appearance“
4. Both horizontal and vertical pipelines can be used for easy installation;	9. Long service life and high reliability
5. Smooth flow channels and low fluid resistance;

Comparison between H72H high-pressure clamp check valve and swing check valve:

structural form	H71 type clamp type lift check valve	H41 type flange lift check valve
Water hammer pressure	Small, short valve disc stroke, large valve disc stroke
Dimensions and Weight	The structure has a short length, small volume, and light weight, which brings great convenience to the layout of pipelines for valve installation, handling, and storage, and can save a lot of materials and reduce costs	The structural length is very long, the volume is bulky, and the weight is heavy
	The structural length of H71 type is only 1/4-1/8 of H41 type, and the weight absorption energy of H71 type is 1/7-1/20 of H41 type
Fluid resistance	Larger, with a fluid resistance coefficient Zeta of 6.4-2.8	Very large, with a fluid resistance coefficient Zeta of 12-6
Install	Can be installed horizontally or vertically, lightweight, no need to set up supports for valves	Can only be installed horizontally, valves with larger diameters are heavy and difficult to install
Opening pressure	Very small, the valve disc can fully open under a small pressure difference	Small in size, the valve disc weighs more and requires a certain pressure difference to fully open the valve disc
reliability	The valve is a monolithic structure, simple and compact, with low impact force when the valve is closed, low water hammer pressure, long valve life, and high reliability	High reliability, but the valve is composed of a valve body and a valve cover, which adds a potential leakage point
