HH48X micro slow closure butterfly check valve Overview:
mainly used for water, source water, sewage, sea water and other media supply, drainage pipe, installed in the pump outlet, to cut off the backflow of the medium to eliminate atomic energy bad water hammer, protect and channel, the safe operation of the pump.
Its main features:
1, small size, light weight, the length of the structure is only about one-third of the swing check valve.
2, the slow closing system has good performance, not affected by the medium quality of the pipeline, the valve disc is closed quickly and then closed slowly, which can prevent the breaking water hammer.
3, rubber soft seal, good sealing performance, wear resistance, long service life.
4, rubber buffer, stable opening and closing, no vibration, no noise.
5, than the old check valve flow resistance is small, has obvious energy-saving effect.
