Product overview:
HQ41X sliding path roller type check valve uses the rubber covered roller as the disc,when,under the action of the medium,
can roll up and down a long with the integral sliding path inside the valve so as to open or close it.It features by good
tightness ,silient close and no production of water hammer .The body is full water-flow path design,big flow ,small resistance and the water head loss is smaller that of the swing type by 50%.
It is mountable vertically or horizontally and can used for cold-water,hot-water,industrial and living sludge pipe networks,especially suitable for the submersible sludge pump .The medium temperature:0-80℃

Ball check valve uses bowl classified covered by rubber as valve disc. With the help of medium, the valve disc can roll up-down or right-left to close or open valve. It can avoid water hammer and has good sealing. The valve body adopts the whole water channel, having large flow and low fluid resistance. Head loss is less than swing valve by 50%.
