H76 Wafer Double-Disc Swing Check Valve

The H76 series is specifically engineered for high-flow pipelines—DN40 and above—where installation space is restricted. It features a dual-disc symmetrical swing mechanism combined with an ultra-thin wafer-style mounting design, offering three core advantages: adaptability to large pipe diameters, extremely low flow resistance, and smooth, stable opening and closing operation. The valve discs consist of a pair of symmetrical, curved plates that pivot synchronously around a central dual-pin shaft; once fully open, the discs sit flush against the inner wall of the valve body, ensuring an unobstructed flow path.
