Wafer Type Dual Plate Check Valve

CHAODA Valves Group is specialized in manufacturing Wafer Check valve(Ranges from Class150 To Class900, PN10 To PN160) with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. Wafer check valve consists of Valve body, disc, stem, spring and etc with wafer type connection ends. Wafer type check valve could obviously reduce the happening of water hammer with its quick closing together with the structure of spring loaded. As the Face to face dimension of Wafer Check valve is smaller than other types of check valve, it's very suitable to act as the device to prevent the backflow of medium in pipelines served in the Water supply & drainage system of urban, industry and top buildings, environmental protect area, water treatment and etc.

Sludge Dewatering Screw Press

Sludge Dewatering Screw Press

HLDS Multi-disc Sludge Dewatering Screw Press belongs to the screw press, it`s clog-free and can reduce the Sedimentation Tank and sludge thickening tank, saving the cost of sewage plant construction. HLDS using screw and the moving rings to clean itself as clog-free structure, and controlled by the PLC automatically, it`s a new technology that can replace the traditional Filter Press like Belt Press and frame press, the screw speed is very low, so it cost low power and water consumption in contrast to the centrifuge, it is a cutting edge sluge dewatering machine.
