Slightly Resistance Ball-Like Check Valve uses the rubber covered roller as the disc, which, under the action of the medium, can roll up and down along with the sliding path inside the valve so as to open or close it. And it features by the big flow, small flow-resistance loss, good tightness, silent close and reduced water shock wave. It can be mountable vertically or horizontally and used on the outlet of the water pump of the cold-water, hot-water, industrial and living sludge pipe networks to prevent the medium from going back.
