Product introduction:

Hh49x / hh48x butterfly silencing slow closing check valve is an ingenious addition of a set of oil control slow closing mechanism based on the butterfly check valve widely used at home and abroad, which uses the self pressure of the medium of the pipeline to slow down the closing speed of the valve disc, so as to achieve the purpose of reducing or eliminating water hammer. The valve has unique and novel structure and excellent performance. It is an advanced product in China at present. It is mainly used in petroleum, chemical, food, medicine, water supply and drainage and energy systems. It is installed at the outlet of water pump to cut off the backflow of medium, eliminate destructive water hammer and protect the safe operation of pipeline and water pump.

Product features:

1. Small size, light weight and structural length is only about one-third of that of swing check valve.

2. The slow closing system has excellent performance and is not affected by the medium in the pipeline. The valve disc is closed quickly and then closed slowly, which can prevent destructive water hammer.

3. Rubber soft seal, good sealing performance, wear resistance and long service life.

4. Rubber buffer, stable opening and closing, no vibration and noise.

5. It has less six resistance than the old check valve and has obvious energy-saving effect
