Detailed Description

DN50-DN300 double flange rubber ball check valve for Sewage 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 - - - - Nominal diameter | 50-300mm | 50-300mm | 50-300mm | Nominal pressure | 1.0mpa | 1.6mpa | 2.5mpa | Shell test | 1.5mpa | 2.4mpa | 3.75mpa | Sealing test | 1.1mpa | 1.76mpa | 2.75mpa | Air seal test | 0.6mpa | 0.6mpa | 0.6mpa | Applicable temperature | 100 | 100 | 100 | Applicable medium | water | water | water | - - - - 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.
